(meteorobs) Fwd: large bolide over California/Nevada

[Jim Wooddell]

Hi Bill and all!

I believe that there were two events that were minutes apart.

3 meteorite hunters were located in the desert near Bouse, AZ and we all 
heard two sonic booms, minutes apart.  Each indicated large objects because 
we were hearing both the bow and aft sounds of each event.

Are there any auto recordings recovered for that time event?

For whatever that is worth.
It "sounds" like I need to get busy and install an outdoor SkyMic!


Cheers!

Jim

This was a BIG event - see below for energetics as calculated by the Meteor 
Physics Group at Western University in Canada.
