(meteorobs) Great Job by Peter and Margaret Campbell-Brown on NOVA!

[Skywayinc at aol.com]

Don't know how many of you had the  opportunity to see NOVA on PBS 
last evening regarding the February Russian  Fireball.  A very interesting
and engaging hour, featuring Peter and Margaret  Campbell-Brown's
analysis of the mass and trajectory of the associated  asteroid that burned 
through
our atmosphere and created a significant sonic boom  about three minutes
later.  
 
This program will no doubt be repeated during the  upcoming
week on various PBS outlets; don't miss it!  Check  your local listings.
