Hi All,

Is someone keeping track of all the guesses for the classification
of the new Norwegian fall? ;-) I guess I can go back through the
archives and collect them all.

Based purely on statistics of falls, I'd be disinclined to join the
chorus and pick carbonaceous chondrite. An ordinary chondrite is
far more probable. That said, this doesn't much look like an H-
or L-chondrite. But equilibrated LL works for me.

If I had to pick a carbonaceous type, I would rule out CB, CH, CI,
CM, CV and CR. That leaves only CO and CK, and it looks more like
a CK to my eye than CO. CKs are also very paramagnetic. --Rob

CO3s can be quite 'magnetic'. Acfer 333 -CO3- for instance is more
attracted by a magnet than a LL and a bit less than a L O.C., so I would
agree with those who already suggested that it could be a CO3... But of
course, nothing sure specially when having seen only pictures! I guess
that the red magnet on the picture belongs to Morten Bilet and must be a
strong one. Cheers,
