The same as any other recovery, if looking on a snow covered lake,
unless there is something special about the number "about 1", which
could be 0.50 g to 1.49 g the way the description is written. One
shepard I spoke with who witnessed a real fireball I chased described a
sandy wind that blew in his face as he heard some whizzing sounds in
the nearby trees. Someone else nearby independently complained of
grains of sand hitting his galvanized metal laminate roof and
windowpanes.

Unfortunately the terrain was not as forgiving as a bright white snow
net over a lake, neither for contrast nor other magnetic dust. If it
had been I certainly would have found similar residue from that
detonating meteoroid, probably in much lower quantities in many
instances.

Also, Tunguska, though on a large scale, is a similar even, isn't it?

Kindest wishes
Doug

Hi List,

While nosing through the Met Bulletin today, I noticed a witnessed
fall with a TKW of only one gram! Is this correct, or is it a
mistake? What are the chances of someone finding 4 small fragments
that add up to one gram?

What makes it more interesting is that the fall was a rare carboncaeous
type.

Does anyone have any more info on this meteorite?

Best regards,
