An ungrouped chondrite is a chondrite with properties that do not fit
into the existing named groups. Right now, this means it is not an H, L,
LL, R, CI, CM, CV, CO, CK, CH, CB, CR, EH, or EL chondrite. It is
something different. There are many ungrouped carbonaceous chondrites,

does that fit with them being Aten or Apollo asteroids which orbit in

Here is the classification for the meteorite that was recovered from
the June 1998 Casa Grande fireball. I just want to say thanks to
several people. Rob Matson and Marc Fries for the Doppler radar work.

The ANSMET yield is Interesting from a statistical perspective. If
anyone thinks NWA is not high-graded in Morocco, then think again!
Makes you spoiled, darn! just Howardite -- I had hoped it was a Lunar

My guess is that the largest piece will weigh 21 kilograms. I will go further
and guess over 1,200 kilograms will be recovered this Spring when the snow

Hi Graham,
Keep in mind that asteroid orbits are dynamic, and that most of
the Apollos, Amors and Atens of today once had their aphelia
between Mars and Jupiter. Planetary perturbations and resonances
over the millenia caused those orbits to evolve into earth-crossing
(or in the case of Amors,
