[meteorite-list] Re: Entry Burn [was Lunar Burn]

[E.P. Grondine]

Hi Chris, list

I have seen two entrie.  I believe I posted the first
one to the list, and it was green - at the time I was 
in Virgina, and the entry was so green I first thought
that it either had to be

a)an accidental launch warhead entry
(which I stopped thinking when nothing exploded), or
b) a piece of space junk.

But it was neither, if I remember the news reports
from the time - no space junk announcement from NORAD,
and press pieces (as always, of dubious reliability)
that it was a meteorite.

The second entry I saw about early December, 2003.  It
should have been over Ohio, I was driving west thtough
the Winchester Gap.  No green tinge at all on this
one, just big.

I like Elton's observation that it is probably the
nickel.  This agrees well with the recently observed
entries of small pieces of SW3.

good hunting,
Ed
