Good evening Folks,

With all the hoopla (and rightly so) about this newest fall, I haven't seen
any of the specimen for sale on the List.  It seems to me that the first few
grams would do very well.  Lots of folks are waiting.  Who will be the first

[meteorite-list] Too Few Lunar Meteorites

2003-03-21 Thread Julien . Courtois
From Sky and Telescope!

March 20, 2003 | It's been 20 years since planetary scientists first
realized that chunks of the Moon and Mars were practically falling into
their laps as meteorites. And, while thankful for the free samples, they've
always puzzled over why these two worlds are represented roughly equally on
Earth. To date collectors have snatched up 24 distinct meteorites from the
Moon (some of which were found in multiple pieces or paired with other
finds) and 28 from Mars. 

The puzzle arises because the lunar specimens should outnumber their Martian
counterparts by more than 100 to 1. For one thing, the Moon's weaker gravity
means that a much smaller impact will accelerate lunar debris to escape
velocity, compared to the more energetic (and thus rarer) blasts necessary
to eject something from Mars. Calculations performed several years ago by
Brett Gladman (University of British Columbia) show that, once launched into
space, a chunk of lunar rock has about a 50-50 chance of ending up on Earth
- 10 times better odds than for an arrival from Mars.

CATCHING ANCIENT STARDUST

Scientists have discovered a rich source of interstellar dust that they
can study right here in labs on Earth. Tiny bits from beyond the solar
system, dating from before the solar system was formed, have turned up in
meteoric dust sifting down from space.

The vast majority of meteorites that reach Earth are too small to see.
Microscopic ones settle to the ground all around us as fine dust,
unnoticed by anybody except the scientists who regard them as a bonanza
for studying interplanetary material. The dust bits don't get burned by
the kind of fiery plunge through the atmosphere that larger meteorites
undergo. They are so small that the upper atmosphere stops them in their
tracks before air friction has a chance to heat them up.

For more than two decades, NASA has collected cosmic dust samples on
oil-coated plates flown by a U2 plane at altitudes of some 65,000 feet (20
kilometers). Now, aided by new diagnostic equipment, scientists have found
that some micrometeorites contain another bonanza

RE: [meteorite-list] The rarest meteorite

2003-01-16 Thread Julien . Courtois


 Now the question:
 Whoever knows if there migh be somewhere hidden (in a museum, 
 collection, or
 just cited in the literature...) some even more rare 
 meteorite, rare being
 based on similar criteria as above, thus combining location, 
 tkw and type,
 to take just these three and simplify. 
 Just a challange..
 

Interseting challenge, I'll take it!

Most of us have rarer meteorites than these two from the moon!

Do you remember, there is a type of meteorites called howardite, supposely
comming from the soil of Vesta.

In these meteorites, it is not so uncommon to find some small black
inclusions. If I remember well they are related to carbonaceous
meteorites...

So I have something rarer (based on location of find, tkw and type) than
these two from the moon!!

Challenge #2: what is the rarest meteorite in your collection? 
Mine is probably the Sahara 98111, a Diogenite with only 29g of TKW

Julien

 Bernd, Dave and list,
 
 I concur with the comments to date. But I thought it really 
 wasn't meteorite
 until the council says it is? For now it is just a rock, right.
 
 My gut tells me that science as a whole is missing the boat with the
 NWA's...someday the negative positions taken during these 
 times over the
 lack information like location, particulars of find, etc. 
 will be a mistake
 that can't be fixed. I know this subject has had a lot of 
 press, but from a
 simpletons point of view the treatment of the most NWA's not being
 legitimate is wrong. I have no clue as to the fix(es) for the problems
 perceived, but to putoff or shun the likes of Dean and others to get
 classifications done in a timely matter is a mistake. Some 
 dealers have
 direct connections that make this less of a problem...but 
 they are in the
 minority I would think. A concerted effort to improve all 
 aspects of this
 problem, including the availability of labs capable of doing such work
 should be done before we lose the bulk of potential 
 information on these
 great rocks. It is late in the game, but not too late I would 
 hope. There
 are many great pieces out here that are orphaned at this 
 point...with owners
 wanting to know what it is.
 
 Protesting not to buy or acknowledge this so called junk only 
 reinforces
 this stubborn position. Those doing so are adding to the 
 thick crust of the
 objectors...limiting science instead of improving it.
 
 From the sounds of it, fixing the problems (some real, some 
 perceived due to
 association) in Morocco are probably the hardest to 
 resolve...and they may
 never be. But once the rocks are in hand, why can't the 
 community come to
 grips with helping all of us with the classification process.
 
 This is my two cents. I am newbie to all this, collecting 
 only for three
 years. I'm sure many smart people out there have more 
 insight.  But when you
 break it down in my mind, the general treatment of NWA's (and 
 other African
 meteorites) is WRONG!
 
 I read an article written in May by fellow list member 
 Norbert Classen that
 discusses this issue from another field collectors point of 
 view. I totally
 agree and hope others will come forward to help this 
 situation out. The link
 is http://www.meteorite.fr/en/news/feature.htm
 
 Thanx for your time and forgive me if you are offended,

[meteorite-list] An Inexpensive Rooftop Fireball Patrol

2002-08-12 Thread Julien . Courtois

Hello list,

I cannot remember to have seen this article mentionned on this list:

http://skyandtelescope.com/news/current/article_679_1.asp

BTW, is Ed still on this list?

An Inexpensive Rooftop Fireball Patrol
By David L. Chandler

  
Edward Albin's fireball monitor keeps an eye out for bright falling stars in
the skies over Atlanta, Georgia. Meteors brighter than 1st magnitude are
recorded by the video camera mounted above the fisheye mirror. Courtesy
Edward Albin 
 
   
July 29, 2002 | The whole thing cost just more than $200, it requires
virtually no maintenance except a once-a-month dusting, and it provides a
useful service that hasn't been widely available before. And it may just be
the start of something big: an all-sky, all-night fireball monitoring
program. 
Edward Albin, an astronomer at the Fernbank Science Center in Atlanta, built
and set up the video system two months ago on the roof of his home just
outside Atlanta (to avoid the city's light pollution at the science center
itself). Having received many calls from the public over the years with
reports of apparent fireball sightings, he decided that it would be useful
to have a way to check back when such accounts come in. He could then both
confirm that it was indeed a fireball - potentially staving off some UFO
reports - and provide details of the meteor's time and heading. Similar
systems have been set up by Sandia National Laboratory. 

Albin built the simple setup from a hemispherical, acrylic corner mirror
like the ones that help you avoid shopping-cart collisions in the
supermarket. He mounted the foot-wide (30-centimeter) mirror horizontally on
a cut-to-size piece of plywood, and secured it with a silicone adhesive.
Initially condensation occasionally formed on the mirror, but that problem
disappeared after Albin put a small electric heating pad inside the dome. 

  
Edward Albin's fireball monitor would easily snare bright meteors such as
this Perseid captured by Russell Sipe. Notice the color changes in the
tail. Courtesy Russell Sipe. 

A simple metal-rod tripod supports the downward-pointing video camera above
the mirror, providing a full-sky fisheye view. The 12-volt, black-and-white
CCD camera, obtained from a surveillance video company, has a sensitivity of
0.0003 lux, allowing it to pick up stars to 1st magnitude, Albin says. The
camera is enclosed in a piece of PVC pipe with a cap for weather protection.
Once a month, he goes up on the roof to clean the apparatus, which mostly
means removing spider webs. 

The images are captured on a standard VHS recorder in the house, connected
by standard coax to the setup on the roof's ridge line, using 8-hour tapes
(up to two per night in winter). At present, he checks the tapes only if
there is a fireball sighting. 

An informal network of such simple and inexpensive devices could make it
possible not only to establish the time and direction of any fireballs
observed in the area, but potentially to triangulate the paths and get
detailed elevation and position data, Albin says. But even individual
monitors can provide useful information at relatively low cost. It is
amazing how many fireballs and bolides have escaped capture on video, even
in our modern techno-gadget age, he says.

Hello list,

I just wanted to share my few impressions!

First of all, it's a quite warm day here in Europe (about 34°C or 93°F for
those using these old units ;-). Anyway, the camel they took to fit with the
moroccan meteorites was perfectly happy!

There was a lot more quality material (SNC/Lunar/HED/...), and much less
ordinary chondrites than last year. Nothing really new anyway! Bensour was
present, but not in really large quantities.

To name a few sellers I met: Michael Farmer, Jim Strope, Carion, La memoire
de la terre, Michel Franco, the Labennes, 

Sorry I didn't took any pictures!

And last but not least, the Meteor beer was fine and the medieval menu was
quite interesting too!! They should be serving wild boar tonight.
