(meteorobs) Fireball Gas cloud? or micro-Particles?

[Chris Peterson]

Larry-

It's completely normal for the products of a fragmentation to appear 
stationary, because they nearly are. The only thing that keeps a meteoroid 
traveling at high velocity against huge drag forces is its mass. Small 
particles have their forward velocity reduced to nothing almost instantly. 
That's why you don't find small meteorites much forward of the terminal 
explosion, and often you can find them behind that point due to atmospheric 
winds.

I've also recorded many fireballs with an asymmetric disintegration like you 
see in your image.
