Re: (meteorobs) Upsilon Pegasids anyone? (Really: non-IMO shower velocities)
Lew asked:

Lew, I don't know how accurate this is (I didn't have time to check more
recent figures), but according to H. Povenmire (1980): "The apparent
velocity is slower than that of the Perseids and faster than that of the
Delta Aquarids. The range was estimated at 50-52 km/sec. The figure of 51.0
km/sec appears to be correct."
I don't really know of any 'one source' for non-IMO showers. I use several,
and am always on the lookout for more to add to my pile. My suggestion would
be to post questions about a specific shower here to meteorobs.
