[meteorite-list] SUTTER'S MILL in MetBull

[Jeff Grossman]

It is important, and we really needed to get the name announced in order 
not to impede science (e.g., the MetSoc abstracts are due in a matter of 
days) and to end the controversy around what to call it.

If you read Zolensky's description in the bulletin, it's clear that he 
thinks the meteorite is CM like.  But it is not your normal CM2 from 
this description.  This could ultimately go a number of ways in the 
final analysis... anything from a CM to an ungrouped C chondrite, or 
maybe something else.  There is no reason to jump to conclusions.  I'm 
betting that the MetSoc abstracts will tell us much more.
