(meteorobs) Correction to previous Trig.calculation.

[Chris Peterson]

I would say that the meteor never stopped ablating (luminescence without 
ablation is essentially impossible). My interpretation of this event is 
that the body penetrated deeply and simply burned up. I've seen many 
fireballs that follow this pattern. Only some show terminal explosions. 
This one seems to have fragmented and lost a lot of mass earlier in its 
path.
