Re: (meteorobs) Re: Point meteors and DCVs
Bob, Mark,
Please explain to me what you two are talking about. What exactly is DCV? When
Bob say his DCV for all magnitudes is averaged at 25 degrees, what exactly does
that mean?
I seemed to see about as many point meteors as Mark indicated, but once I
realized seeing them also involved reasearching satellite positions (to discount
that possibility), I began hoping that I would not see any unless they came
straight out of known, active radiants. Just too much additional work for a
beginner!

P.S. I wonder if any video observations could give a percentage of Leonids that
were pointers during the storm, and I wonder if that percentage could in any way
be extrapolated to other meteors, even sporadics. Just a pipe dream...
