(meteorobs) Correction to previous Trig.calculation.

[Chris Peterson]

Here are some fireballs I've recorded that all show a similar pattern of 
slow brightness increase, some flaring or fragmentation, followed by a 
gradual decrease in brightness. All of these had moderate descent 
angles, meaning that they definitely burned up in the atmosphere, and 
that the atmosphere was becoming increasing dense over their entire 
flight.
