(meteorobs) Addendum to Natural Meteor...

[Larry]

The "fragmentation" that is often apparent in photographic movies is usually 
the broad ablation light of a meteoroid illuminating the dust on mirrors, 
lenses, and domes as the object moves across the sky.

Unless INDEPENDANT fragment motion or direction(fall) can be observed, or 
particle dying light that fades AFTER meteoroid is well beyond the point of 
illuminating any dust in that vacinity on the camera system, it should be 
assumed to be a lens dust artifact.

It does take very close image scrutiny looking for the above characteristics 
to avoid this apparent deception when arriving at a fragmentation 
conclusion.
