Re: (meteorobs) Re: bolide explosions
Thanks to Howard for a great question, and George for a very helpful (and
vivid) response. It sure seems like George's description serves to explain
fragmentation and (I guess?) concussive sounds. But how can this model of an
exploding dirt clod produce the terminal bursts or (even stranger) MID-FLIGHT
bursts which are often noted in fireballs? These are the sudden, nearly point
like brightenings seen along a meteor's path, which can raise the meteor's
maximum brightness as much as 3 or 4 magnitudes - a tremendous outpouring of
energy! Is it that when the dustbunny explodes as George describes, there is
some kind of very sudden conversion of all its kinetic energy - or what?
Clear skies and many bolides!
