(meteorobs) Re: Pointer Meteor Definition



Peter,

The point meteors that I have seen seem to but truly points without any
length whatsoever. On the other hand I also have a distinct lack of
meteors between zero and one degree long too! I would have to agree with
Lew's mention of Norman's definition that it must be less than 2 arc
minutes when seen close to your the center of your field of view.

Rob's mention of angular velocity and Lew's of DCV's are also both valid
points. If I recollect correctly all of my point meteors (less than 5
out of 50000) have been seen very close to the center of my field of
view.

Clear Skies!

Bob
