Peter and List....

All nine Chelyabinsk/Chebarkul individuals that I have purchased from three different foreign sources resemble themselves. The specimens I have look like they could have come out of that pile that Mike Farmer posted. Mostly small individuals of less than three grams, black even fusion crust, no other coloration, regs, no cracking except for a few fracturing in flight with the result that the interior lithography is covered by black fusion product. None but a few that I've seen so far show more than the smallest impact marks and those display a typical grey chondritic, almost Portland cement color. Most landed on snow so have remained pristine. Heavier pieces will be recovered when the ice and snow melt. They are strongly attracted to a neo magnet and set off a detector easily, so I'm a little curious about the initial classification I've heard. Is LL6 S1 W1 and named Chebarkuhl..correct? Anyone...Ted?

Send me your email address, Peter and I'll shoot you a photo.

Regards,
