Thanks for the plot!  I kind of suspected it may have been
an observing effect.  Bob Verish pointed out to me that in another
eyewitness case (not Park Forest), a fireball was observed to
be travelling 'up'.  This can happen with the right viewing perspective with
a low-angle flight path, even though the fireball is really falling down.

Again, the DOD data indicates the strewnfield is
larger then originally thought, particularly along the true flight path.
I think most of the obvious fragments have been recovered, but people
should now be looking in the less obvious or less accessible areas (ie:
private country clubs).  For instance, some of the pieces may have fallen in 
soft ground and may be buried, or in areas where there is more vegetation.

[meteorite-list] DoD Satellites Detect March 2003 Bolide Over Park Forest

2003-07-13 Thread Matson, Robert
Hi All,

Regarding the discrepancy between the apparent bolide trajectory
(SE --> NW) as derived from the Park Forest strewnfield data, and
the NNE trajectory reported by DoD sensors, Steve Arnold wrote:

I think I can lay to rest any concerns that there was a mistake
in the DoD report -- the bolide did indeed travel from SSW to
NNE, and far from contradicting the eyewitness accounts, it is
in complete agreement with them.  You see, with a trajectory
this steep coupled with the lack of range information (observers
on the ground can really only measure "apparent" bearing), it
is not possible to accurately determine the true bearing from
one observer's viewpoint.  For observers south of Chicago, the
trajectory defined by the DoD report will indeed result in a
meteor that appears to be headed almost due northwest.  To see
for yourselves, download the following .GIF file that I generated
with my SkyMap program:



SkyMap has a rocket trajectory mode that allows me to plug in
times, latitudes, longitudes and altitudes for a trajectory.
I took the DoD linear impact coordinates (41.56 N, 87.67 W)
and back propagated a 20-km/sec constant velocity path using
the 22.3-deg flight azimuth and 62.3-deg-from-horizontal
flight path angle in the report. (Don't pay too much attention
to the time-tags -- I decelerated the bolide somewhat below
10-km altitude so that I could get a few more points on the
track.  This doesn't affect the track direction, just the
spacing of the times.) The bottom line is that despite the
22.5 deg (NNE) true heading, the bolide appears to be heading
toward azimuth 315, which is due northwest.

The observer coordinates I used were 41.5 N, 87.6 W, which is
in the rough vicinity of Chicago Heights.  I can rerun the
program for other specific observer coordinates if anyone
is interested, since the apparent trajectory is very sensitive
to observer location.

Cheers,
Rob

Hello Mike and List, 

Sorry for joining this conversation late as I was out the last few days.

At this point I am still reluctant to share too much information as I still have Park Forest specimens to sell and I am convinced many more little ones are out there waiting to be picked and compete with mine in the market place.

However, I will say, after picking up 113 specimens and probably spending 30% of my time (of the 44 days I hunted) looking outside of the strewnfield area on my map, these things are very uniformly distributed (with one little exception - all the oriented specimens landed with significantly smaller sized stones) from sub gram pieces roughly in the Southeast and the big 5kg one roughly to the Northwest.  And this field goes MUCH further southeast than most people realize. Much more than the 1/4 to 1/2 mile that Mike mentioned above.  Also the further Southeast I got the more dramatic the reports were of the noise, light and shaking when the rocks came in. 

I do not think any meteorites fell in Beecher.  Reports from one person said multiple pieces hit their window and or roof top.  I think not.  Maybe the sonic boom(s) shook the windows and roof, but if "many" pieces could land on just one roof, or hit just one window, we should have tens of thousands if not hundreds of thousand of small specimen in and around Beecher.  I did not find any near Beecher.  I don't think anyone else did either.  Slag yes, meteorites no.

Within my strewnfield map area, I would find pieces in a fairly constant spacing from each other with a few anomalies of two pieces being found just feet from each other.  Once I would venture out too far in any direction, (one never knows how far is too far until he tries) I would not find anything in 10 times the area I would find a specimen back inside the zone, possibly only a few hundred or thousand feet away.  

Of course there could be more outside of my mapped area, but statically we are looking at about 200 specimens total now and NONE of them are significantly out of place.  I mean if just one specimen was found anywhere to the Southwest or the Northeast of all 200 others, that might make me think it was transported, but it would offer a hint of a possibility of a SW to NE fall.  But there is not one such find.  There were many cars and buildings hit with rocks laying in the street.  If there were any significantly to the SW wouldn't one have been found?  And if there was such a low break up, then the wind would have to be blowing like 500 miles an hour to scoot those specimens miles to the East with rocks indeed going in under roof eves and hitting windows.  

As I mentioned before in another post, this is a very normal elliptical strewnfield.  The only thing that would make it perfect would be a 50kg stone found a mile or two further Northwest of where the other big ones have been found.

Even with the possibility of a reverse strewnfield, that would need to place the fireball coming in from the NW going SE.  Match that up with the eye witness accounts that Steve Witt mentioned, and I would have to say that there is an error in the report.  I know, it is totally impossible for some people to think that anyone who works for the government could ever be wrong about anything.  Humm... maybe this is a conspiracy by the Federal Government to throw us all of the track of the real main mass waiting to be located...

Oh, on another subject, Noe Garza's 911 call came into the Park Forest Police Department at 11:56pm of the 26th.  Maybe the dispatcher's clock might have been off by a few seconds or possibly a minute, but even with a little variation, I am now convinced that the fall distinctively was on the 26th.  It would be interesting to know if Garza could account for how long it took for the rock to hit his house and then for him to actually make the call.  It is still looking like a 3 minute plus free fall after burn out before impact.

Frank,
 
It is unlikely that kind of detail would be available to anyone with less than a secret clearance . . . and they wouldn't be able to tell us either. Detailed data reveals capability; DoD protects from exposing thier capabilities as much as they can. Basically, we're lucky to get what we get.

Hello list,

Would it be possible for someone to get enough data from the DOD satellite
detection to determine initial velocity, final velocity at extintion, and
altitude at extintion to help resolve (wishful thinking, I know) this part
of the Park Forest debate?  Is this something that the DOD might release, or
might they release enough raw data for one of the more upstanding,
trustworthy, researcher types on this list to make that calculation?

If the wind data is still available, it may be good to model
the fall with winds in different altitudes. It´s quite amusing,
how strong the effect of the wind could be in smaller fragments.

We had a very promising bolide in Finland in February, and
in first modellings we forgot the wind. In the modellings with
wind data the smaller fragments (about 50 grams) changed
their direction over 140 degrees before landing...

take care,

HI,
I guess I should correct myself before someone else does. 
When I read the initial report about the direction of the fall I misinterpreted its message, and somehow turned a N.E. approach into a S.E. approach in my mind, accounting for my total perplexity! The relevant satellite information does no indicate the opposite of what I thought after all, but is slightly skewed to the east.
This is only a minor adjustment, and brings about a whole new hunting perspective! Perhaps it's time to go get another rock or two.  : )

Also, if the fall is SW to NE, and so far we 
see most small stones to the south and south east of the large stones, would 
this not also be affected by upper level winds? High winds can cause the 
smaller stones to drift, meaning that this strewnfield would thus be

Yes, strewnfields can be reversed, Portales

If you shoot the same rifle twice with two different

bullet will hit higher than the smaller bullet. But, if instead you shoot the

If you shoot the gun at the ground at a 70% angle, they will also hit the same

Tom,
The strewn field data proves otherwise, there is a distribution according to weight as best I can see.

Also, if the fall is SW to NE, and so far we see 
most small stones to the south and south east of the large stones, would this 
not also be affected by upper level winds? High winds can cause the smaller 
stones to drift, meaning that this strewnfield would thus be perfectly normal. 

 
Yes, strewnfields can be reversed, Portales Valley 
was a perfect example, without exception, the largest stones all fell to the 
back and the small stones fell later. This is due to low exploding of the 
meteorite forcing the larger stones down.

  Hi Al,Yes I saw the the meteorwrongs in his

  convince me that they were meteorites when I told him they were slag. I asked 
  if he was including them in his data and he said no. Is that really true? I 
  don't know. He did have some nice individuals and fragments however, and 
  claimed his strewn field info came from real meteorites,some gathered by

  that were sold by the local Postmaster, who supposedly got most of his stones 
  from another man I met out there that was a local, and rather proficient at

  not be completely reliable, the fact remains that the larger stones are N.W.

  Hi Mike and List,
   
  I am repeating what I was told by a very informed 
  source and I agree it doesn't make sense.  Since I have only seen three 
  partial plots that need to be merged I can not see the reversal effect that is 
  being authored by another List member, maybe he will comment.  What I did 
  notice is three large clusters or concentrations on the plots which I 
  found very interesting.  Now that the direction issue has been solved I 
  wish they would have reported the retardation altitude.

Hello Folks,This whole thing has me a 
bit perplexed for several reasons. First, the stone my brother and I 
recovered had a distinct angle of entry that I saw and documented, and 
passed on to Mr. Sipiera. That trajectory definately indicated that the 
offending stone came in from the S.E. and was heading in a N.W. 
direction. I determined this before ever being subjected to other 
theoriesof direction of entry. I also spoke with eyewitnesses in the 
days that followed and all backed up that conclusion.On a second 
trip I met with a man named Atul Kumar, He isn't a scientist but he has 
been gathering info on the strewn field for the astronomy club that he 
is involved with. He has compiled quite a list/map of stones that were 
recovered, including weights and locations of recovery, and his map 
indicates the same S.E. to N.W. direction, with the larger stones coming 
from the N.W. end of the strewn field. Of course I can't argue with 
the DOD satellite observation, but it sure is contradictory to what I've 
been thinking all along! The satellite indicates an entry of exactly the 
opposite of what the strewn field maps look like that I have seen, and 
my own recoveries, 70 gram stone in Steger, 638gram stone in P.F. 
indicate at the very least a South to North trajectory, (roughly).No 
matter how you slice it, based on the DOD satellite info, the larger 
stones should be south of the small ones, and this is just not the 
case.Is human error possible, between interpretation of the

Atul is a interesting individual and means well but out of all the specimens he had
gathered, I look at several hundred of his pieces and all were slag's that are found
in the area. He then wanted some cut to verify which I did. Very vesicular and not
meteoritic at all. Ironically some do have bits of metal embedded in them but no doubt
from the steel mills or some other fabrication places from the area. No doubt used as
fill and so forth in the region. He did have a couple of nice individuals that were
real and interviewed a number of people who had stones fall in their yard.

His data might be incorrect if he is including the non-meteorites which I examined and
had a hard time convincing him they were not related to the fall. All my best!

Re: [meteorite-list] DOD Satellites Detect March 2003 Bolide Over Park Forest

2003-07-08 Thread Sterling K. Webb
Hi,

A little geometry here, gentlemen. The "aiming point" is not the center of
the strewn field. Assuming that fragments from the breakup have randomized
perpendicular vectors, you have a cone of dispersal oriented along the flight
plan.
Since the flight path is roughly 30% off the vertical, the cone of
dispersal intersects the ground at a 30% angle also. The largest portion of
the strewn field ellipse will be NNE (22.3 degree azimuth is almost perfectly
NNE, which is 22.5 degrees) of the aiming point.
Since Park Forest is six or seven miles SSW of the aiming point, one would
expect the larger NNE portion to extend for 10 to 12 miles NNE from the aiming
point. That line runs (roughly) through Flossmoor, Homewood, Harvey,
Riverdale, one mile west of I-94 from 115th St. up to 103rd St. before ending.

HOWEVER, one must not assume that the majority of the fragments shed or
dispersed originated solely with the final breakup. In fact, the final breakup
may have produced no fragments at all (total burn up)! There were obviously
earlier breakups which occurred further "up" the flight path and whose cones
of dispersal would have been shifted to the SSW.
If the fragments collected in Park Forest were from the "final" breakup,
then the strewn field could extend as far NNE as indicated above, but if they
were from an "earlier" breakup the resulting strewn field, while having the
same shape and orientation, would have a more southerly footprint.
If the largest fragments are from Olympia Fields, it would appear that the
area immediately NNE of Olympia Fields would have larger fragments if it were
part of the strewn field, but it also appears that these areas, being private
golf clubs, were not searched, as I understand it. Did anyone interview the
groundskeepers to see if they had to pick up a bunch of damn rocks off the
fairways?
Since the purpose of these satellites is pinpoint the coordinates and
flight paths of IR-emitting objects and since accuracy is primary (did that
missile come from Kazakhstan or Fiji?), it's silly to imagine it's less
accurate than Park Forest teenagers, pub crawlers, and cops, sincere as their
observations may have been.
And, lastly, as if we needed any more proof of the utter unreliability of
"eye" witnesses...

2003-07-08 Thread Rob Wesel
I am not debating the DOD satellite data, merely pointing out that the known
fall area, every piece I have heard of, fits a line from Olympia Fields to
Beecher. Hence the vise vera. That line goes NW-SE or SE-NW. I find it
interesting that an opposite trajectory angle has no confirmed recoveries
that I know of. Perhaps one of the Steves, Witt or Arnold IMB, can shed some
light on NE or SW recoveries. Any damage, any finds on a NE-SW line?

For those of you who are not familiar with the area, this will help. The
strewnfield based on reported finds and damage as I know it...NW/SE
http://imagehost.vendio.com/bin/imageserver.x//rancor/mapimagecopy.j
pg
I realize in my haste that I put "north" off to the left  a bit when in fact
north is the top of the image.
Again I believe Paul Sipiera is making the master map, and I have not seen
it. While in PF a man named Tim Janecyk was doing nothing but coordinate
mapping with precise map markings that conformed the the linked rough
sketch.

I believe the satellite but where are the meteorites...and why? Even if the
near vertical drop constrained the fall, I see no remenants of the
documented trajectory in the fall pattern.

Very puzzled,

That's consistent with Rob's observations, but the DOD satellite saw it 
traveling SW to NE. I'm not sure why there is a 90 degree discrepancy
in the flight direction between the satellite observations and the 
ground observations.

Or vice versa?  That's 180 degrees in the opposite direction!   It is interesting
you report that way though. It may be an observing effect depending on whether
the fireball was observed from north or south its flight path.

Note that the DOD satellite measured the flight path angle at 62 degrees from
the horizontal, or 28 degrees from the vertical.  That means the meteorite fall 
was more vertical than horizontal.  I think this somewhat vertical flight path 
may have made judging the flight direction 
more difficult from the ground, maybe creating an optical illusion effect. It is 
already 
well-documented the difficulty in judging the distance to fireballs from a single 
location.   Even if the true flight path was SW to NE as the DOD data indicates, and 
this
would extend the strewnfield out to a larger size along the flight path direction, 
the near-vertical drop does constrain the size of the strewnfield ellipse.

I'm very heavily inclined to believe the DOD satellite measurements are more accurate 
than
the ground observations anyway, because the satellite was designed to accurately 
record these type of details.

DOD claims SW to NE, still doesn't fit. Looking from above or below , it
would make the strewnfield an "X".
Distribution is NW - SE.

Olympia Fields to Beecher is 5.5 to 6 miles. If the bigs fall at the end
then the distribution goes SE to NW. I believe Paul Sipiera is working on a

That is interesting because the direction you noted is perpendicular to what the 
DOD satellite saw.  Your distribution ellipse is based on actual finds, so 
combined with the DOD data, this indicates that the Park Forest strewnfield is
actually larger than orginally thought, and many of the meteorite fragments 
have not been recovered, including some of the larger fragments. It would be 
interesting to try to figure out how much your strewnfield ellipse overlaps with 
the DOD ellipse.  The larger pieces would tend to fall downstream on the far end 
of the ellipse, or some kilometers northeast of the coordinate given in the DOD 
report (41.56 North latitude, 87.67 West longitude).  Incidently, how far is 
this position from Park Forest and Beecher?

Note that this is the time when the DOD satellite first detected it, when
it was still airborne and in its fireball phase.  In these DOD reports, when
they say 'impact', they really mean 'impact' with Earth's upper atmosphere, not
the ground.

Chicago is 6 hours behind UTC until Daylight Savings Time
kicks in, then it's 5 hours.  So, that places the time noted
below as 11:50:26 PM on March 26th, which matches my
observation of the bolide.

Ok, Now we know the exact time of the PF fall. Can anyone
convert this to
PF's local time?

2003-07-08 Thread Rob Wesel
The distribution from Olympia Fields/Park Forest to Steger/Beecher would
argue that the flight path was NW to SE or vice versa. The larger masses in
the Olympia Fields area would support the former. If they are correct I was
searching the wrong side of every building. Please enlighten,

Fireball Detection
Department of Defense Announcement 
(courtesy of Peter Brown)
July 7, 2003

IR sensors aboard US DOD satellites detected the impact of a bolide over 
Park Forest, Illinois, on 27 March 2003 at 05:50:26 UTC. The object 
traveled from the SW to the NE on a heading of 22.3 degrees, with a 
flight path angle of 62.3 degrees from the local horizontal. 
The straight line intersection of the flight path with the ground was at 
41.56 North latitude, 87.67 West longitude.  It was possible to derive a 
velocity for the object of 20 +/- 1 km/sec.  The impact was simultaneously 
detected by space based visible wavelength sensors operated by the US 
Department of Energy.  From these sensors the total radiated energy was 
estimated at 1.4 X 10^11 joules.
