[meteorite-list] re: Mystery Surrounds Green Meteor in Australia

Hi All,

Regarding reentering manmade satellites or "space junk", Ron

Bolide events outnumber manmade debris reentries by thousands
to one.  How many on this list have ever seen a satellite
reentry?  I'd be surprised if the answer is more than one.
On the other hand, I think pretty much everyone has seen at
least one bolide in his/her lifetime.  I've seen more than a
dozen, and despite ACTIVELY looking for satellite reentries --
which are predictable, by the way -- I've never seen one.
 
Ron checked for potential matches to the latest Australian
event:

It's good that you checked, but in this case it was probably
overkill:  the trajectory was from east to west, eliminating
all but a handful of highly retrograde objects.
