Re: (meteorobs) Angular Speed Equations

As Malcolm pointed out, a good angular speed measurement can be used to
roughly estimate the shower radiant position, when combined with the path
length. >>
Yes this can be done for one meteor if desired. But why would you want to
find a rough estimate for a "shower radiant position" with just one meteor? I
don't know anyone who seriously looks for a shower radiant position with just
one meteor in the first place. Meteor intersects is what people look for
initially when looking for possible new radiants. If you have 2 or more
meteors that intersects to give one a reason to think about a possible
radiant position, the position area becomes obvious. This can be done with
the speed scale I use. For new possible radiants though, Usually no one gives
a second look until they have at least about 4 intersects per 50 plotted
meteors whether one uses angular velocity estimates or a speed scale.
Anything less, you will end up with thousands of "new radiants" each year to
needlessly burden yourself with.
