[meteorite-list] Lake Ontario event

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

I re-calculated the 19 Nov 2022 Lake Ontario meteorite fall.  Most of the 
meteorites landed in the lake, in shallow water reportedly less than ~70' deep. 
 Some meteorites up to 230g are seen landing off of Vineland Station but larger 
masses almost certainly fell down-track as well.

[meteorite-list] Meteorite fall New Jersey 08 May 2023

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

Howdy all

  There was a meteorite fall yesterday afternoon in New Jersey, 
with one meteorite falling through a house.  Radar indicates this was a larger 
fall than just a single stone, although overall mass is fairly low.  I am 
working on the data now, but am updating the NASA Meteorite Falls page as I go:

https://ares.jsc.nasa.gov/meteorite-falls/

  Keep an eye on this page throughout the day as I add a strewn 
field and other data.  Good luck!

[meteorite-list] New meteorite fall in Maine

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

Howdy all

There was a noontime bolide over eastern Maine this past Saturday which 
produced a meteorite fall. There was only one NEXRAD radar in range of this 
event but it appears in four radar sweeps, complete with short-range turbulence 
from falling rocks.  Details can be found here:

[meteorite-list] Muskogee kmz

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

I have finished calculating the landing sites for all of the radar signatures 
in the Muskogee fall, and they produced a nicely defined strewn field.  I 
cannot post the Google Earth kmz on the NASA website just because there is no 
file-sharing mechanism there. Feel free to email me at this address and I'll 
send you the kmz file.

The new calculation moves the strewn field slightly east for the heaviest 
masses, and expands the strewnfield slightly south and west.  It looks like it 
was a fairly massive fall.

[meteorite-list] Strewn field for Muskogee

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

The strewn field is now published for the Muskogee event.  This was created 
using the newest version of Jormungandr which is still in mid-validation, so I 
may update it.  Even if so it shouldn't change much.

Evidence suggests large meteorites fell near the airport, in the 100g range.

[meteorite-list] High-certainty meteorite fall on Muskogee, OK

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

Greetings

  It appears that this event on AMS resulted in a meteorite fall:

https://ams.imo.net/members/imo_view/event/2023/374

  The event occurred at 03:38:50 AM local time on 20 January 2023, 
or 0938:50 UTC. It appears in GLM data and in data from four separate NEXRAD 
radars showing signatures of falling meteorites. The bolide traveled from NW to 
SE starting off east of Tulsa and terminating over Muskogee. Tomorrow I will 
generate a NASA Meteorite Falls web page for this event complete with a 
computed strewn field, in the meantime you can visit my Twitter account for 
first-draft radar images of the fall (Marc Fries, @warrantyviolatr - not a NASA 
account!).

  The most massive meteorites probably landed east of the Muskogee 
airport along a line extending to the SE. Winds were out of the SW, so smaller 
meteorites (100s of grams and less) landed in the southern end of Muskogee 
extending towards the NW.  This will be a roughly banana-shaped strewn field 
with the large end extending towards the SE and smaller meteorites extending 
towards the NE.

  More to come in the morning...

Good luck!

[meteorite-list] Meteorite Fall - Grimsby Ontario 19 Nov 2022

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

Yes that same Grimsby.  They get a new meteorite fall for 2022.  Don't get mad 
at me, I just report these things!

Web page is up at: https://ares.jsc.nasa.gov/meteorite-falls/

I am also posting tweets under my own account.  Find it by searching for Marc 
Fries, @WarrantyViolatr  Be advised that this is a personal account and 
contains opinions and comments that are not NASA-approved.

Most but not all of this fall is in Lake Ontario.  Small masses should be on 
the ground east of Grimsby, and larger ones might be on land near McNab.

[meteorite-list] Update on 24 Aug 2022 Colorado event

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

I have posted a NASA page for the recent Colorado event:

https://ares.jsc.nasa.gov/meteorite-falls/events/coalmont-co

This is a POSSIBLE meteorite fall.  It only produced one radar signature but I 
am including it because the signature is fairly strong and features short-range 
turbulence.  Having only one signature reduces confidence that this is a fall, 
but the appearance of turbulence makes it more interesting.  Also, the Denver 
mineral show is coming up and some folks have contacted me stating that they'd 
be interested in investigating this event as part of a trip to that show.  So, 
here it is - good luck!  I hope it is a fall.

[meteorite-list] Interesting radar signature - Colorado bolide, AMS event 5337

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

Howdy

  I've found something interesting in radar data from the 24 Aug 
event over Colorado and would like to ask for input.  All radar observations of 
this event were from moderate to long range as the relatively nearby Cheyenne 
radar was down.  The Front Range (KFTG) radar shows a strong signature in a 
single sweep that may be worth investigating. It appears in the 0233 data set, 
in the 1.80 degree sweep.  The signature is just west of Coalmont, CO.  It is a 
strong radar reflection with short-range turbulence as seen in the Velocity 
data.

  The signature appears along the ground track calculated by AMS.  
It occurs about 4 minutes after the AMS time and appears to have short range 
turbulence. These are factors which point towards a detection of a meteorite 
fall.  It only appears in one radar sweep, although KRIW may have also picked 
it up in the 0234 data set, 1.32 degree sweep.

  Thoughts?

Cheers,
Marc Fries

[meteorite-list] Great Salt Lake meteorite fall, 13 Aug 2022

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

After a series of computer-based misadventures, I have (finally) posted a NASA 
Meteorite Falls page for the Salt Lake City meteorite fall:

https://ares.jsc.nasa.gov/meteorite-falls/

To date more than a dozen meteorites have been recovered.  To the best of my 
knowledge they were all on the western shore of the Great Salt Lake, but it 
appears some smaller meteorites may also be found on the eastern shore quite 
close to Salt Lake City. The meteorites recovered to date have trended to 
masses in the hundreds of grams.

Be very careful hunting this fall.  The ground is recently-exposed lake floor 
and is soft and wet. Temperatures are high and there are no drinkable water 
sources. People have reported getting trucks and off-road vehicles stuck, and 
it is a long walk to the nearest road. Use good desert survival practices and 
bring lots of water. Sources such as the National Park Service can be of use in 
planning a safe trek:

https://www.nps.gov/subjects/healthandsafety/trip-planning-guide.htm

[meteorite-list] Much-delayed notice of UT meteorite fall

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

I have been on international travel for almost two weeks, and the loaner 
computer I was using "bricked".  I've been without a computer or email for 
almost two weeks as a result.  On 15 August I sent an email to the List from my 
phone to try to get the word out, but that apparently didn't work.  Here's the 
original email again, and now that I'm back in the States with a working 
computer I'll generate a strewn field for the Salt Lake City fall ASAP.

Cheers,
Marc Fries

Original email:
Greetings

I am on international travel with a bricked computer and am trying to get 
word out about a possible Utah meteorite fall. This was a daytime bolide of 13 
August.  I will have difficulty working on this event until I return stateside 
in almost two weeks, so others need to jump in and check this event.

   Radar signatures appear in higher elevations of the KMTX 1428 radar data 
set. They are mostly visible in the Velocity data because the radar is nearby 
and there is interference from ground clutter and weather. They appear roughly 
parallel to and north of I-80 along a track that approximately matches both the 
AMS ground track and GLM signatures. The ground track of these radar signatures 
is long, but that appears to match GLM data showing a low entry angle, fairly 
long ground track. I see signatures consistent with fast-moving meteorites in 
five radar sweeps (between 4 and 12.4 degree sweeps).

Videos of this event show a fast moving, bright daytime fireball. I'm 
surprised to see radar signatures given the apparent speed, but they appear 
reasonable for a meteorite fall. The ground track is partially over the Great 
Salt Lake and partially over shoreline not far north of I-80.

[meteorite-list] Meteorite Fall observed - Natchez MS 27 April 2022

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

A remarkable meteorite fall has occurred east of Natchez MS.  This event was 
widely reported in media because loud sonic booms were reported over a wide 
area.  This was a daytime fireball and a single video (as far as I know) has 
emerged on Twitter.

Weather radar records a nearly vertical column of falling meteorites, seen in 
at least eleven radar sweeps in at least four separate radars.

https://ares.jsc.nasa.gov/meteorite-falls/

It is currently the front page item for the NASA Meteorite Falls page.  At 
present no meteorites have been recovered to my knowledge, but I assign a high 
certainty that meteorites have fallen.

[meteorite-list] Fredricksburg TX event 29 Jan 2022

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

Howdy all

  We've had a bunch of fireballs with dozens of AMS eyewitness 
reports over the last couple of months.  In going back over them I found a 
really nice one that escaped my notice:

https://fireball.amsmeteors.org/members/imo_view/event/2022/740

  The videos of this event show an exceptionally long-lasting 
fireball (~14s) with pronounced fragmentation.  It appears that multiple 
objects slow down towards the end of the fireball. This appears to be a good 
candidate for a meteorite fall.

  Searching the radar data yielded some interesting signatures 
~35km NW of Fredricksburg, TX on the KGRK, KEWX, KDYX, and KSJT radars.  None 
are especially strong but they seem to cluster.  I cannot find any pronounced 
surface features, windmill farms, radio towers, or other reflectors at this 
site.  I will draw up a NASA Meteorite Falls page for this event and share 
images once I'm happy with the data refinement.  In the meanwhile, could y'all 
have a look?  This one may be promising.  There is a signature on KSJT in the 
1.49 degree sweep, 0602 data set, which appears only 40s after the fireball 
terminus.  Jormungandr calculates that it corresponds to a/an 11.1kg 
meteorite(s).

[meteorite-list] Update: Meteorite Fall outside Patch Grove WI 20 Jan 2022

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

Howdy all

  After parsing through some more data I've convinced myself that 
there was a (probably small) meteorite fall near Patch Grove, WI on 20 January. 
 NASA Meteor Watch (look them up on Facebook) reports that this fireball was 
very slow-moving, near the lower limit of infall velocities for meteoroids.  
This makes for a relatively weak fireball and enhanced chance of meteorite 
survival - but it also means this could be a small body that wouldn't have 
survived if not for the low speed, and few meteorites were produced.  On radar 
I see radar signatures from falling meteorites of mean masses 2.8g and 0.2g, 
seen on two different radars (KARX and KGRB) which improves confidence in the 
detection.  Seismic data shows a relatively weak sonic boom, and only one AMS 
eyewitness reported hearing this one and it was electrophonic noise and not a 
sonic boom.  It does not show up in GLM data.
  All told, my conclusion was this was a small body that produced a 
small fall, largely on account of its very low infall speed.  The ground is 
mostly farmland and should be favorable for recovery.  It might be best to 
focus on finding meteorites in the sub-100g range, but that is just my opinion.

NASA Meteorite Falls page is up:

https://ares.jsc.nasa.gov/meteorite-falls/

If you have trouble with the website try using a phone.  I can't see it on my 
computer but it shows up fine on my phone.

Good luck!

[meteorite-list] Possible meteorite fall, WI 20 Jan 2022

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

Howdy all

  AMS' meteor event 512 may have produced a fall, as there is an 
interesting radar signature that matches in time and place:

https://fireball.amsmeteors.org/members/imo_view/event/2022/512

  The bolide was traveling from NE to SW according to AMS.  I've 
found one video of the event:

https://www.youtube.com/watch?v=a3xfNG_jLlo

  Radar shows a signature at 5km AGL altitude, just west of the 
town of Patch Grove, WI.  I'd prefer to see signatures on multiple radars and 
altitudes to build confidence that we're seeing a fall, but this single sweep 
does look similar to those seen in previous falls.  Its' altitude probably 
precludes interference from birds, and it does not have the traditional shape 
or intensity of a reflection from an aircraft.  It is also almost exactly at 
the terminus end of AMS' ground track estimate.  The event does not show up in 
Geostationary Lightning Mapper data, and it produced a fairly weak signature in 
a seismometer approximately 50 miles away. All of these add up to a small 
meteorite fall, but probably find-able given that the terrain is mostly 
farmland.
  I'll draw up a NASA web page for this event, but wanted to pass 
on the news so you all can start talking about it.

  Fun factoid - the radar signature for this event is only 35 miles 
from Mifflin, WI.

Howdy all

I have found some interesting radar returns associated with the New 
Jersey daytime bolide on 13 Nov 2021.  I am sending this email as advance 
notice that more information is coming, and to give as much time as possible 
for others to start looking into the data.  This is AMS event number 7611 for 
2021:

https://fireballs.amsmeteors.org/members/imo_view/event/2021/7611

I believe the ground track in the AMS report is incorrect for two 
reasons.  One, if you look at the highest-confidence eyewitness reports with 
directions turned on, you'll see that they are reporting a ground track much 
further to the south.  Two, if this event followed the AMS ground track then 
there should have been many reports of sound in the NJ/NY area.  There are none.

Also, go look at "NASA Meteor Watch" on Facebook.  I can't link to it 
here but they report a ground track much further south, terminating near Cape 
May, NJ.

I found some very interesting radar returns near Cape May, THEN looked 
at NASA Meteor Watch and found their ground track bullseyes the radar returns.

Furthermore, NASA Meteor Watch reports that this bolide matches the 
expected speed and direction for a body originating from the Taurid meteor 
shower which is currently active.  These bodies originate from Comet Encke.  
Therefore, this event may be a cometary-origin meteorite fall, from a known 
comet no less.

At this point I have found signatures in data from two different 
radars.  I'm taking the unusual step of stopping my own analysis long enough to 
spread this word.  If you work with video, radar, seismometer data, or any 
other form of meteorite fall research, I suggest you look closely at this event 
and let's start a discussion.

Back to the data...   I will put up a web page on this event on NASA 
ARES' website ASAP.

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

Howdy all

Re: the 16 Oct 2021 daytime fireball seen in video from Tucson. On 
further examination, the expanding-ring feature on radar appears to be birds 
leaving their roosts at daybreak, and it is just a coincidence that it appears 
in the same 10-minute GLM exposure as the bolide.  
GLM data need to be processed to produce the actual ground track - this 
event shows up on both GOES East and GOES West imagery, and each one imposes an 
error in actual position based on the viewing angle of the satellite.  NASA 
Bolides normally does this analysis, but they're slow.  Right now their most 
recent events are from mid-September: https://neo-bolide.ndc.nasa.gov/#/   It 
looks to me like the bolide terminated in northern Mexico from the GLM data, 
but again - someone who actually knows how to correct their data needs to have 
a go at it.
I drew up an azimuth towards the terminus using the train station video 
and Google Earth, and it does appear to coincide with the terminus location 
inferred from GLM data.  At this point I'm thinking the terminus, was in Mexico 
approximately 40 miles south of the US border.  The video also shows that the 
fireball was quite fast, which may explain why AMS eyewitnesses were all over 
the place with their azimuth reports. It also, of course, decreases the 
likelihood that any meteorites reached the ground.
I searched for seismometer signatures for this event and came up empty, 
but there was only one nearby seismometer with data available yesterday.

[meteorite-list] Daytime fireball 16 Oct 2021

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

There was a daytime bolide over the AZ/NM/Mexico area this morning (16 Oct 
2021) at 1323 UTC which may have generated a meteorite fall.  The American 
Meteor Society is reporting it here: 
https://fireball.amsmeteors.org/members/imo_view/event/2021/6611

At the time of this writing, the AMS is reporting a ground track just east of 
Tucson. This event shows up clearly on both the GOES East and West satellite 
data, in the Geostationary Lightning Mapper (GLM) imagery, but with a ground 
track that appears to be farther to the SE and in northern Mexico. 

NOAA weather radar imagery from the KEPZ radar (El Paso, TX) reveals a striking 
feature which appears near the location suggested by GLM and at the time 
reported by GLM and eyewitness accounts.  This feature is a rapidly-spreading 
circular feature centered on: 

107.9987°W 30.7232°N

This feature appears as an expanding circle at low altitude, moving at 30 mph 
outward in all directions following the time of the bolide.  This circular 
signature may be birds scared into flight by the sonic boom. This same bird 
feature is visible in radar data for the Monahans and Indian Butte meteorite 
falls. No falling meteorites are obvious, but the event occurred at long range 
from the radar and the weak radar signatures of falling meteorites may not 
appear.  

In summary, GLM, eyewitness, and weather radar data indicate that a meteorite 
fall may have occurred in Mexico near the coordinates listed above.  This site 
is populated and features a few farming communities, with the "El Chocolate" 
dry lake bed to its south.  Conditions should be good for recovery of 
meteorites.  Analysis of radar data will continue.

[meteorite-list] Washington SpaceX fall event

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

I've posted some data on the Washington debris fall from last 26 March.  Radar 
signatures from this event persist for about two hours after the event, and 
some early-arriving signatures appear to be massive objects.  The strewn field 
lies along a line which covers most of the state and appears along a line which 
roughly connects Yakima and Spokane.

Re: [meteorite-list] [EXTERNAL] Meteorite-list Digest, Vol 222, Issue 24

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

AMS reports four significant fireballs over the weekend: 
https://amsmeteors.org/2021/03/four-fireballs-spotted-during-the-week-end/ 

I checked the three stateside events on NEXRAD radar and couldn't find anything 
convincing.  The Pennsylvania one does show up in GLM imagery, in the GOES-16 
satellite image at 04:20 UTC.  Radar tells the same story I've been left with 
many times, though - there's a few pixels here and there that might be 
something, but its not enough to tell a consistent story.  

I'll insert my usual caveat - a small meteorite fall may slip past the radars 
undetected.  There are a few examples, such as the New Orleans fall which was 
evidently a single stone.

Cheers,
Marc Fries

Hello friends,
I imagine many of you must have seen the increase on facebook, twitter, etc. of 
several post including fake photos about a "meteorite on eastern Cuba". No 
meteorite has been recovered, it was just a fireball.
I have the data, but I need a fireball expert to help me better interpret the 
data to prepare an explanatory note. Please direct inbox, thanks!

Try as I might, I can't find radar signatures to go with the recent event in 
Vermont.  Has anyone had any luck with it?

Re: [meteorite-list] [EXTERNAL] Re: Galactic Analytics content?

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

Howdy all

  Thank you all for your feedback.  I've been talking with folks on 
various platforms today, and it seems I've found a good option.  There is a new 
meteorite-related, international, non-profit organization standing up soon.  
They've agreed to host GA-style information including images with free and open 
access.  What I'd like to do, if it's alright with y'all, is to host content on 
that platform and send links to the Met List.  That way y'all can share in the 
content, the information remains freely available, and this also solves the 
problem of how to share images (strewn fall calculations, images of radar 
signatures, etc.).
  This new organization is going to make its debut online in about 
a month and will have their own announcements - I don't want to steal their 
thunder by saying more than that now. It looks like this is going to work well.

  If any new falls occur between now and then, well I'm working on 
that.  I'll find a way to disseminate that information.

Cheers,
Marc

Hello Marc

This Meteorite List has terms of service as well, and has removed individuals 
based upon their postings. It would be a shame if our precious meteorite list 
was dragged into an ideological debate as we have struggled to keep the List on 
topic in the past.

Even though this List is not a democracy, I vote no on your proposal as briefly 
described.

Announcements are fine, I believe, as long as they abide by the TOS, but an 
increased traffic flow is concerning if it deviates from the spirit and purpose 
of this List. Perhaps more clarification about your proposal is needed.

Best wishes

[meteorite-list] Daylight fireball, TX-OK 18 Apr 2017

[Fries, Marc D. (JSC-XI211) via Meteorite-list]

Howdy all

There is a recent event in the AMS logs for a ~1 PM fireball.  
This event seems to have passed directly over DFW headed NE.  It looks to me 
like the ground track was rather long, as reports from DFW spotted the fireball 
both SW and NE of DFW.

http://www.amsmeteors.org/members/imo_view/event/2017/1407

There is an interesting radar return in the KSRX (Fort Smith, 
AR) 18:12 UTC radar data, in the 2.4 degree sweep.  It is a very “bright” 
reflection for a meteorite fall (if that is what it is), with a strong 
turbulence signature and a “flat” spectral width* that are favorable for a 
meteorite fall interpretation.  This return lies exactly along the ground track 
ID’d by eyewitnesses, just SW of the town of Hugo, OK.  There are four other 
radar returns that might also be associated with this event, in that they line 
up along the AMS ground track.  I will post information on the Galactic 
Analytics page on Facebook, along with maps.

My read on this is – the KSRX return outside Hugo is consistent 
with the fall of a small number of relatively large objects, of sufficient size 
to generate a strong turbulent wake in their path.  I’m not sure about the 
other radar returns; they could just be random noise.

Cheers,
Marc Fries

*Spectral width is a measure of the range of object sizes in a given radar 
image pixel, and meteorite falls usually have low SW values of about the same 
value; or “flat” SW values.

[meteorite-list] Request for assistance

[FRIES, MARC D. (JSC-XI211) via Meteorite-list]

Howdy ladies and gents

I am working with summer intern Colleen Laird from Case Western Reserve
U. to develop mathematical tools for quantifying meteorite falls from
radar data.  Colleen has made superb progress and we should soon be able
to offer estimates for the total mass that falls in any given meteorite
fall, the percent that is actually recovered, and possibly provide some
insight on the type of meteorite that falls from its radar behavior
(maybe!).  To do these things, we need to calculate the mass of meteorites
seen in previous meteorite falls, and to that we need accurate time stamps
for the fireball terminus (e.g. The point when a meteor goes dark).
Terminus altitudes are useful too, but we really need the times as
accurately as possible.

Of the meteorite falls Colleen is working on, we don¹t have an accurate
time stamp for the following ones.  Could I ask y¹all to dig into your
videos and notes for these events and look for terminus times?  We will
produce a paper and make it available, and should be able to estimate the
total mass reaching the ground for future meteorite falls.

Cheers,
Marc Fries

[meteorite-list] Salt Lake City fireball images?

[FRIES, MARC D. (JSC-XI211) via Meteorite-list]

Howdy all

Back on 18 Nov 2009 there was a huge bolide over Salt Lake City, UT:

https://www.youtube.com/watch?v=hJFejgd9bSE

The following morning, locals reported seeing high-altitude dust
lingering over the city.  At the time I figured it was a coincidence, but
in retrospect I think the dust very well may have been debris from the
fireball.  

Does anyone have any pictures of the dust?  I recall that one was passed
around a bit, but I can¹t find it now.  I¹d like to use the image in a
science presentation, and will (of course) give credit for the image to
the owner.

Re: [meteorite-list] Did I Capture Bolide During SpaceX Launch?

[FRIES, MARC D. (JSC-XI111) via Meteorite-list]

I don¹t think it is a bolide, because at 1:07 something goes from right to
left in the same area, coming from off-frame to the right.  I think you¹re
looking at something making a loop; a bird, nearby bug, or perhaps a
drone.  Still, I¹ll look at the radar imagery and see if anything shows
up.  Do you know what direction you were facing at the time?

Cheers,
Marc

Re: [meteorite-list] Huh? PhD has a Meteor? over Houston, TX?

[FRIES, MARC D. (JSC-XI111) via Meteorite-list]

Theoretically, sure; a bolide could skip out of the atmosphere and return
on a second pass. Or at least I¹ve been told this by people who¹ve spent
more time on it than myself and I tend to believe them.  But in that case,
³slow moving² is not an option.  You would need a very fast-moving,
massive object that A) retains enough velocity to continue on after the
atmosphere slows it down, and B) has enough mass to survive the
atmospheric ablation. And I would expect it to be a mechanically tough
body, since even one fragmentation event would probably be the end of its
journey. You¹d get something more like this:

https://www.youtube.com/watch?v=7M8LQ7_hWtE

So we¹re back to a fast object again, certainly not something that someone
can video for more than three minutes like the guy did in Houston. I¹m
certain the Houston event was an airplane.

Marc Fries

I concur; airplane contrail.  If I wanted to, I could point out how close
they are to a NASA center that hosts experts on the subjectŠ  Nah.

True!  Sorry; what I meant to say was that there are no eyewitness reports
-=of an actual meteor=-. Unless I¹ve missed something, this is true for
all eyewitness reporting sites.

Re: [meteorite-list] Meteorite-list Digest, Vol 138, Issue 15

[FRIES, MARC D. (JSC-KT111) via Meteorite-list]

Howdy, all

I¹ve examined this event and I don¹t agree that this feature is a debris
cloud.  It is visible in radar imagery about 15 minutes prior to the
eyewitness accounts of sonic booms. It is also missing some of the
diagnostic features of a meteorite fall, namely internal turbulence that
fades within minutes of the event, high-altitude signatures, a sequential
appearance due to size sorting of falling debris, and other features in
the various radar data products. This feature moves laterally the whole
time it is visible and appears prior to the event; looks like weather to
me.
There is a feature just NE of Shreveport that is interesting but not
conclusively a meteorite fall.  There are turbulence features seen in the
Shreveport radar and reflectivity features seen at long range from the
Fort Polk radar.  I¹m not convinced that these features are related
either, but we are talking them over. One feature of this event that
troubles me is that there aren¹t any eyewitness reports on the AMS
reporting page. Even though the area was overcast, an event of this
magnitude should have been visible over a very large area. In the past,
events like this have turned out to be man-made events coming from
something on the ground.

Cheers,
Marc Fries

Re: [meteorite-list] Wisconsin Meteorite Hunt.

[Fries, Marc D (3225)]

I was wondering if this was going to turn up on the mailing list or not...  We 
arrived at this property, obtained permission from the landowners to search it, 
and were approached by this gent who was upset because he was there before us.  
It doesn't work that way, and in any case it's up to the landowner to give or 
deny permission to hunt.  Ironically, we had just left a parcel of land where 
four other groups/individuals came and went while we were searching it.  We 
stopped and chatted cordially with a few of them, shared information, and all 
had a Coke and a smile without undue snippiness.  Sonny didn't do anything 
wrong here, and it is my observation that he is a very conscientious gent whom 
I would be happy to hunt with again.

Cheers,
Marc Fries

[meteorite-list] Wisconsin

[Fries, Marc D (3225)]

Howdy all   

I've returned to my "day job" from a trip to the WI strewn field.  I 
arrived with my boots worn in, and left with my boots worn out!  Even though I 
left without finding a stone, I had a magnificent time and would gladly do it 
all again. I got to participate as other members of our field party found a 
couple of very nice meteorites and finally got to meet several folks from the 
list in person.  Thanks to all of y'all for a wonderful trip, and may you find 
many more stones.  Many thanks are due to the galactically friendly, patient 
locals who made me want to move up there. And Sonny, good luck selling that 
meteorite with the trilobite in it - you know, the one that hit the mailbox and 
bounced off of the cow.  I hear they're not worth much if there's a chip in the 
fusion crust like that.

Cheers,
Marc Fries

I love that idea!   I like how it emphasizes some of the best  
attributes of meteorite hunting - public outreach and just plain  
getting people excited about this stuff.  Solves the problem of  
multiple Livingstons as well.

Re: [meteorite-list] Livingston, WI fall

[Fries, Marc D (3225)]

My take on the radar data includes a generally NW to SE track.  This  
event shows up on three different radars!  Magnificent stuff.

Re: [meteorite-list] PARTLY CLOUDY WITH A CHANCE OF CHONDRITES -STUDYING METEORITE FALLS USING. DOPPLER WEATHER RADAR

[Fries, Marc D (3225)]

Howdy

   I'm glad y'all are enjoying the abstract.  I've been looking forward to
that one, and I'm actually working on the poster to go with it as I sit
here.  I'll add another one to Rob's list - Portales Valley shows up in data
from multiple radars, although they are all at extended range and short on
detail.
   I'm glad to see the run-down of y'all's contributions to this stuff as
well.  Rob didn't mention it but he's the one who first noticed the Park
Forest radar detection, and I'm glad to see this sort of "stone soup" effort
overall.  The more meteorites we can get in out of the rain, the better.

Re: [meteorite-list] Lovina Iron

[Fries, Marc D (3225)]

What a beautiful meteorite!  My first take on it is that it must have
crystallized directly from a melt.  The pyramidal forms looks like dendrites
complete with a preferred orientation.  Dendrites do not form in solids like
Widmannstatten patterns do ­ they form by solidification from a liquid.  If
that¹s what we¹re looking at here and not just some sort of
corrosion-etching effect, then it appears that this solidified directly from
an iron/nickel melt without significant recrystallization afterwards.   It
will be fun to see what comes of this.  I think we all know that photographs
never tell the whole story.

Marc Fries

 There was a lot of discussion at the Tucson show about the Lovina
 Iron Meteorite found in Indonesia in 1981.  It was first determined
 to be a meteorite, a very unusual meteorite in appearance.  Then
 news came out that it was possibly not a meteorite.  Anyway, the
 partslices looked so cool that I got one off of Darryl Pitt in
 Tucson.  I knew full well that the jury was still out.
 
 Well, just received news this morning from Darryl that it is now
 back to being a meteorite.
 
 Check out the photo of Lovina before cutting:

 I bet everybody that got a piece of this will be really stoked.
 Congrats Darryl.

Re: [meteorite-list] Fireball over Tucson 2-16-2010 7:28pm

[Fries, Marc D (3225)]

First off, I¹m back!  We had a very successful ANSMET season this year and
collected 1010 meteorites (with probably a few terrestrials in there).  The
weather was spectacular and allowed us to put about 750 miles on our
snowmobiles while searching.

As for this meteor ­ I¹ve pulled the radar data but I¹m going to need a
better positional fix.  That radar outside of Tucson is notoriously ³noisy²
for some reason.  I¹ll work on this further to see if something obvious pops
up in the meanwhile.

Cheers,

Re: [meteorite-list] Biophysicist confirms Liberal boy's meteorite discovery

[Fries, Marc D (3225)]

That hole has definitely been dug up.  But it also doesn¹t appear to be a
foot deep.  Perhaps in a 10 year old¹s imagination it is.

I just ran the numbers, and if we assume a spherical body (which I have to
do) moving at its aerodynamically-limited speed then a 48 g iron meteorite
would be moving around 70 m/s (~150 mph) when it reached the ground.  I can
picture it digging itself in a bit on impact.

Like Mike, I¹m not going to proclaim this one to be the genuine article but
I¹m also not ready to dismiss it completely.  I¹m curious to see how it pans
out.  Would be nice to get some composition data to compare it with SA or
other meteorites.

[meteorite-list] New fall with radar signature - up for grabs!

[Fries, Marc D (3225)]

This one appears to have produced a strewn field approximately 20-25 km in
length with a very prominent smoke trail.  First one there can have it!

36.7990 N ­122.8979 W

And it looked like this (scroll down to ³sunset fireball²):

http://www.spaceweather.com/archive.php?view=1&day=10&month=11&year=2009

This critter spent four billion years or so floating in space only to drop
into the ocean within sight of land.  That¹s a bummer, because the radar
signature is impressive.  Anyone have a submarine?  Or just a really long
pole with a net on it?

Well ain¹t that a hoot - I sent him the same images a couple of weeks ago.
I even used the same background image!  Peter Brown probably thinks we're a

I'd say there's a potential return in the next data set at about 2.5 km
altitude, but it is down in the noise and open to interpretation.

Re: [meteorite-list] Nickel tests

[Fries, Marc D (3225)]

I've also had mixed results with the nickel allergy kit, but I think I've
figured out how to get reasonably reliable results.

I think the problem is that the companies who make these things probably
have liability lawyers telling them to err on the side of false positives
(which won't really cause them trouble) rather than on sensitivity (which
might put them in court defending against a false negative result).  This
means that false positives will occur.

You have to liberate nickel from the sample to detect it.  Weathering can do
this for you, which means that you might not detect nickel in a fresh sample
face, especially for a polished iron meteorite.

So here's what I've found that seems to work:

- start with the unknown sample and a known meteorite - an NWA unk will do
as long as you are sure it is a meteorite
- place a drop of vinegar on both samples
- wait five minutes, so that the acid will dissolve some nickel
- do the nickel test on both drops of vinegar
- wait five minutes, and don't get excited if they're both red at first
- compare the results

In the event of a false positive, the swab will start out red and then fade.
The known meteorite should stay red.  If they both stay red and look about
the same after five minutes, you've got a good case for nickel in the
unknown sample.

That's my take; I'm certain there is a lot of experience out there on this
topic.

Cheers,
MDF

Re: [meteorite-list] Block Island

[Fries, Marc D (3225)]

You¹d first have to convince me that, in the entire span of time that this
rock sat exposed on the surface, the winds were never (even once) strong
enough to move them along sufficiently to leave them on top of the rock.
Bear in mind that the entire surrounding terrain is covered with wind-blown
dunes.

On the other hand, it seems reasonable to me that the meteorite was once
buried in this terrain and has been exposed, possibly leaving the little
pebbles behind.

Re: [meteorite-list] Mike Farmer Eats Moon & Mars Rocks!

[Fries, Marc D (3225)]

The gent who wrote the Red Mars trilogy, Kim Stanley Robinson, wrote a short
appendix to one of the books in the series.  The details are a little
sketchy to me now (been a while since I read them), but if I recall
correctly the appendix was titled, ³The First Recorded Instance of
Aerophagy² and was about him sitting on his rooftop looking at Mars while he
ate a small piece of a martian meteorite.  I recall being stunned at the
time, but I wouldn't even blink at such a thing today.

Re: [meteorite-list] PA fall media hype

Okay, now let me see if I've got this straight...   You're sitting there
rubbing your hands in glee and cackling over your own private pile of
freshly-fallen stones, saying that the key to recovering as many meteorites
as possible is to get the public involved...

I can't agree more!  How 'bout some coordinates?  Might not suck to have a
small army out there before the rains come.  ;-)

Meanwhile I'll start holding my breath, because blue is my favorite color.

Re: [meteorite-list] How far away can a meteor be heard?

[Fries, Marc D]

That¹s a good question.  There's one major difference between a
meteor-produced sonic boom and thunder - altitude.  Most thunderstorms occur
below 10 km altitude while fireballs occur well up in the 20-30 km range.
That means that the fireball should propagate to a wider area, but it seems
in practice that their sonic booms are highly directional.  I think its a
bit of an apples-to-oranges comparison, since thunder radiates
omnidirectionally from low altitude while fireballs "push" a compression
wave ahead of their direction of travel at a much higher altitude.  Thunder
also propagates without seeing much in the way of change in air pressure,
while fireball sonic booms radiate downward through a pretty substantial
increase in air pressure.

So my answer is...   It depends.  (Which is almost always the answer to a
scientific question!)  People directly along the path of a fireball should
hear something louder than those off to the sides, I would expect.  In
principle a fireball's sonic boom should also travel farther since it starts
higher up, but I suspect that propagating downward and outward through
increasingly thicker atmosphere would serve to deflect and diminish it.

I bet that research into airburst nuclear weapons blasts included modeling
of shock waves and would be very useful for answering that question, but I'm
thinking that we're not going to get a look at that data any time soon.
Just a hunch.

I second the motion.  In the event that no meteorites turn up, a sample of
freshly fallen fine debris should be sufficient to identify the meteorite by
type if nothing else.

Re: [meteorite-list] Military intelligence-- still an oxymoron.

[Fries, Marc D]

Yeah, I saw this article.  For some reason the press tends to go
extra-special whenever they report on military matters.   My favorite part
is this:

>> 
>> The upshot: Space rocks that explode in the atmosphere are
>> now classified.

Yeah, that's it.  You're not allowed to know that meteors exist.  Why, that
makes perfect sense, and I'm sure that's exactly how the rule change was
phrased.

It seems more likely that someone decided that a clever observer could
discern important details about our technical capabilities from the
information handed out to meteor watchers and decided to clamp down.  It may
be a temporary change while they review the policy, but you can't tell from
that magnificent piece of professional journalism.

Magnificent.

Re: [meteorite-list] Black Diamonds: A interesting PBS NOVA article

[Fries, Marc D]

Howdy Stirling

You get nanocrystalline diamond from nitrogen in the source
gases/liquids.  This happens because nitrogen will substitute for carbon in
the diamond crystal lattice, but it brings an extra electron with it.  The
crystal solves that problem by incorporating a vacancy defect for every
nitrogen defect.  Add enough nitrogen and you wind up with diamond that is
loaded with defects and won't grow large, clear crystals - exactly what you
see with carbonadoes.  Nitrogen also multiplies the growth rate and the
nucleation density, so the whole thing grows quickly as diamond goes - as
much as mm's per hour.  Note that that growth rate most likely discounts
formation in the initial fireball after a large impact.  It also doesn't
matter how the diamonds are made - nitrogen will have the same effect.

Carbonadoes are very cool.  They're also maddening, because we've got a
lot of data about them but there are multiple reasonable explanations for
most of their attributes!  I'm glad to see all this interest in them, and
I'm pretty confident that someone will "solve" them in my lifetime.

Now, back to my place at the oars...

Cheers,
MDF

Re: [meteorite-list] Black Diamonds: A interesting PBS NOVA article

[Fries, Marc D]

Wish I¹d seen this one when it came out; I¹d have gladly written a rebuttal
paper.  Not quite sure how they can claim there is a "complete absence of a
deep Earth fingerprint", especially since they point out the low delta-C13
values in carbonadoes themselves.  The same range of values is seen in
reduced carbon from both terrestrial and martian igneous rocks, as other
papers have noted.  Nitrogen has been noted in mantle fluids numerous times
as well and could easily be the source of the nitrogen in carbonadoes.  I've
never seen "planar defect lamellae" in a carbonado, which this paper
mentions but doesn't show.  Planar defects can be simply the result of
strain while buried, and only for silicates have the criteria for
distinguishing strain-induced lamellae from shock-derived PDF's been
established.  All of the features of carbonadoes can be explained by
formation in a deep-Earth environment from carbonaceous fluids or gases with
the caveat that it would have to be a very reducing environment.  There are
two comments to be made about that - 1) that very fact has been used to
explain away the possibility that a natural reactor is the source of
carbonadoes, and 2) it would be a rare environment, but that is consistent
with the fact that carbonadoes have basically only been found once in
Earth's historical record.  It also only requires a casual perusal of the
mineral record to see examples of extremes of both reducing and oxidizing
environments in the Earth's crust.

Beyond this note, I'm really too busy to get into this.  Carbonadoes are
very cool and still mysterious, but I have yet to see a convincing argument
that they are extraterrestrial.  I've examined a few myself and found them
to be a marvelous oddity, but a terrestrial oddity.  I certainly wouldn't
evoke an asteroid-sized diamond impactor to explain them.

Re: [meteorite-list] Neither Carbonado Nor Meteorite

[Fries, Marc D]

A carbonado with fusion crust?  My skepticism meter is pegged.  If true it
would be of extraordinary scientific interest, but the problem is that
diamond doesn¹t melt.  It evaporates.  Silicates are content to form what is
basically a liquid silicon oxide, but carbon oxides (CO, CO2) are gases, not
liquids.  Diamond doesn¹t flow ­ it goes poof.

I looked at those pictures, and there are little spallation flakes on one
side that remind me an awful lot of a carbonate rock.

Caveat emptor.

MDF

[meteorite-list] Note to anyone searching for the VA Beach fireball

[Fries, Marc D]

Howdy all

I haven¹t heard from anyone searching for meteorites from the Virginia
Beach fireball from last week, so I¹ll post this for general consumption.
If anyone is there, could you collect samples of meteorite particles for
analysis?  By that I mean covering a magnet with Saran Wrap (or its
equivalent) and drag it through some house gutters or along the drip line of
a large building.  If you'll wrap the plastic wrap over itself and send it
to me I'll finagle some time on an SEM and/or electron probe to identify the
meteorite type (hopefully).  Radar shows that fine debris settled to the
ground on the southern tip of the Delmarva peninsula with the help of strong
winds from the southeast, and even if all the sizable pieces turn out to be
fishy squishers we can at least identify the type of meteorite involved from
the tiny bits.
Contact me off-list to set this up, por favor.

Cheers,
MDF

[meteorite-list] West strewn field

[Fries, Marc D]

Howdy, all

I lost track of who was producing the strewn field map for the West
fall, so I need to send this out to everyone.  Any word on when that map
will be available?  It would be very helpful to compare it to the radar data
and start work on a method of predicting strewn fields from radar returns.
I think that would be of benefit to everyone.

[meteorite-list] Radar signatures associated with the VA Beach Fireball, 29 Mar 09

[Fries, Marc D]

Howdy ladies and gents

I have looked over the radar data from the VA Beach fireball this past
Sunday (I¹m calling it VA Beach because that was the location of the closest
eyewitness).  I believe there is a consistent debris trail in the data.
This track in the data evolves over a forty minute period and trends towards
the ESE, while all the clouds in the radar data move in a ENE to NEN
direction.  Either the debris was generated below the jet stream or we
over-estimated the effects of the jet stream, but that is something for me
to figure out later on.

Here is my data from that meteor.  Click on each image for a
description:

http://s653.photobucket.com/albums/uu251/mfries/

The available eyewitnesses converge well as to the direction of the
fireball.  Note that the VA Beach astronomers estimate the distance ­ the
last radar return is only 20 km removed from their estimate.  The debris
trail appears mostly over the Chesapeake, but the farthest downrange portion
crosses the Delmarva peninsula near the town of Johnsontown.  The western
end of the track (i.e. the first radar data to appear) also appears over
land (just barely) near Stingray Point, VA.  Note that this is uncorrected
for wind drift.  Surface winds were out of the SES at 5mph with 20 mpg gusts
(from Norfolk, VA met data), and I placed a crude correction of 3.3 mi on my
Google Earth image (5mph over 40 minutes after the fireball reports).
Basically, the position of the debris cloud should indicate a northeastern
limit for the actual position of fallen meteorites.

My brother hasn¹t had a chance to look this over yet; I¹m jumping ahead
of him a bit because I¹m reasonably convinced that I¹m looking at a meteor
trace in the data.

Disclaimer: Be advised that this information comes with no guarantees of
any kind and represents my interpretation only.  This is provided for
information purposes only, and neither I nor JPL assume liability for costs
and/or personal harm that may arise from personal decisions based on this
information.

[meteorite-list] High winds aloft during east coast fireball last night

[Fries, Marc D]

Howdy all
 
 My brother and I did a preliminary assessment of weather and radar
associated with the fireball yesterday evening, and things look grim for the
home team.  The jet stream was directly over Norfolk with 100-120 kt
(185-225 km/hr) winds out of the SW.  Dominant lower level winds were ³well
organized, strong and deep² following on the passage of a cold front a few
hours previously.  The reduced radar data set available today doesn¹t show
anything out of the ordinary for local weather, which is reasonable
considering the high winds that should be sufficient to quickly dissipate a
debris plume.

Considering this one was described as moving NE from Virginia Beach, VA,
it sounds like a Fishy Squisher anyways.
 
 We¹ll have another look when the radar archives refresh.  I hope it
pans out ­ I really want to see a refrigerator with North Korean markings on
ebay.
 
Cheers,
MDF

[meteorite-list] Fireball and booms reported - Dorchester County, Md., to the Virginia/North Carolina border

[Fries, Marc D]

Cripes...   So count with me, since 01 Jan: Denmark, West TX, Kentucky,

-nc

Streaking lights, explosions reported all along coast

Were they meteors? A comet? UFOs?

People from Maryland to Hampton Roads heard loud explosions and saw
brilliant, streaking lights in the sky Sunday night.

There was no immediate explanation, the National Weather Service office
in Wakefield said. The Virginia Beach 911 center had numerous calls
waiting just before 10 p.m., a supervisor said.

The Weather Service said reports were made from Dorchester County, Md.,
to the Virginia/North Carolina border. People said they saw a streak in
the sky and heard an explosion.

³It was orange, like a fireball,² said Steve Wagner, who lives in the
Great Bridge area of Chesapeake and said what he saw was too close to be
a shooting star. Wagner was outside cooking with family when he saw the
streak. He said he went inside when his daughter called, then heard an
explosion that sounded like thunder.

Chris Wamsley, a meteorologist with the National Weather Service¹s
Wakefield office, said there could be various causes of the explosions
and lights. A team of people is looking into what happened, he said.

Lindsey Hosek of the Great Neck area of Virginia Beach was jogging along
the water with her dog when the sky lit up, she said.

³The bright light at first terrified me because I thought somebody was
shining a light on me, and then I saw it, and I was in complete awe
because it was so beautiful,² she said.

Then she saw something that looked like a comet moving low toward the
ground; it was blue in front followed by orange and appeared to be the
shape and size of a refrigerator.

³It was just so low. It was like where a bird should be,² she said. ³It
was definitely heading downward.²

She was on the phone with a friend a minute later when she heard an
explosion.

Kenneth Martin of Chesapeake¹s South Norfolk neighborhood said he saw
what appeared to be lightning, then the sky turned blue.

Then, he said, a white ball of fire shot close to the ground and
appeared to burn out. He said he¹s sure it was a meteor.

³It was so vivid in the sky, blinking,² he said. ³It was the strangest
thing I¹ve ever seen.²

No damage was reported, the Weather Service said.

Re: [meteorite-list] Dam Hammer

[Fries, Marc D]

My two cents, Ocause what the hell, eh?  We¹re up to several dollars by now.

Call whatever you want a hammer, because I don¹t think anyone will ever
agree on a ³lower cut-off level of importance² for a hammer-worthy target.
Just include a description of whatever the ³hammer² hit, and let the buyer
decide if he/she wants to pay two/five/a million times as much because it
landed on a roof or a footprint or discarded Snickers wrapper or an [insert
favorite item of monumental importance here].

Actually, I¹d like to see a hammer that actually hit a hammer.  I call dibs.

[meteorite-list] FW: Meteorite over Denmark Jan 17 has been found

[Fries, Marc D]

Howdy all

Thought this might be of interest.  It is from a Danish friend of mine,
and it came with a little postage-stamp of a picture that doesn¹t show much.
Email me off-list and I¹ll pass on the picture.

Here¹s a link to a news item about the fall:

Hey  You,

FYI: The meteorite that fell over DK on Jan 17, and that was witnessed by
over 400 people has been found. Apparently it's a very rare one. The DK
newspaper reports that only 10 has ever been found worldwide and never with
the trajectory described by witnesses. They don't mention the type but I'm
sure it's reported on your 'hit lists'.

Here's a picture of the thingy.

Enjoy your weekend.

Re: [meteorite-list] Unidentified object from sky destroys car in Cottonwood

[Fries, Marc D]

Whatever hit it looks (to me) like it fragmented completely when it hit the
windshield.  The dashboard doesn¹t have one deep gouge in it like a solid
object would inflict; it has a shotgun-spray of spallation damage.  Whatever
hit the thing wound up as tiny pieces scattered around inside the car.  Ice
falling from an airplane, perhaps?  I still think the ³debris² they show is
part of the dashboard.

Oh, and the windshield wasn¹t ³melted² like that genius journo declared.
Windshields have two panes of safety glass glued together with a plastic
sheet in between. That keeps glass fragments from flying around because they
stick to the plastic, just like the photo shows.   The ³melted glass² is
that plastic sheet stretched all out of shape by getting walloped.  All the
journo had to do was touch the thing to figure that out.

Now I¹m really going to quit getting wrapped up in this stuff and get back
to work..

MDF

Eh...   This happened 26 Feb, but didn¹t become a news item until the $10k
offer.  Danger, Will Robinson...

And that debris looks like part of the car dashboard or something to me.
Man-made, anyways.

[meteorite-list] FW: Doppler radar signature from bolides

[Fries, Marc D]

Bear in mind that you only find the big rocks when you walk a strewn field.
Meteors routinely produce clouds of falling sand-grain-sized (or smaller)
debris.  Much of this is in the form of metallic or metal-oxide spherules ­
great radar reflectors!

MDF

[meteorite-list] FW: NEW YORK FIREBALL / Acknowledgement & Gratitude

[Fries, Marc D]

I¹m flattered; thank you.

For those of y¹all who¹ve asked me about the Westchester fall, I am still
working through some ambiguity in the data.  I will send an image to those
who already asked - anyone else can email me off-list and I¹m happy to share
the radar image from that meteor.  Its location and timing are unfortunate ­
two radars other than the Long Island one collected data right up to the
meteor location but didn¹t quite produce a signal.  The Long Island radar
also just missed the falling debris with its first pass, and only caught the
tail end with the second pass ten minutes later.  It¹s pretty, but nothing
like the West data.

Cheers,
MDF

[meteorite-list] Well okay then

[Fries, Marc D]

Howdy all

I¹ve received a few ...em... ³spirited² responses to my last email that
tell me that it didn¹t exactly read the way I intended.  I wasn¹t trying to
be a hero because I bought a plane ticket, I was trying to say that
traveling on ³your own dime² isn¹t what scientists are used to doing.
Someone had made the comment that there were no scientists to be seen at
West, and I agree that is ridiculous.  Scientists travel to Antarctica every
year to collect meteorites, but no one could be bothered to fly to Austin!?
How many people who spend their lives studying meteorites just passed up a
chance to see an actual, fresh strewn field??  (not to mention the kolaches)
Funny thing is, I was actually agreeing with some of the nasty-grams I¹ve
received.  
Sounds like I touched a nerve.  Can I suggest that y¹all spare me the
wrath, and direct it instead at the scientists who weren¹t actually there?

Re: [meteorite-list] West Meteorite tally, PLEASE let's get this one right

[Fries, Marc D]

This scientist could only make it there for one and a half days, on my own
dime, and would have loved to stay.  A downside of our profession is that
most of us have to account for our (fairly pricey) time and don¹t have much
in the way of flexibility.

I¹m very interested in seeing the tally from this fall.  Even better would
be a detailed strewn field map with locations and masses, but even a rough
depiction of the strewn field long axis (axes?) would be great stuff.  Seems
to me that a downside of your profession is that that information is used to
support yourselves and so becomes proprietary.  I understand that, but it is
a real loss scientifically speaking.
