If the Cloud Gods allow, I'll be out doing some dark-sky plotting from about 
July 29 to August 3. I'd like to identify any "Upsilon Pegasids" I happen to 
observe. The snag is that my only source of UPE information is Gary Kronk's 
excellent "Meteor Catalog", and Gary doesn't list radiant drift or geocentric 
velocity data for his non-IMO showers! (Actually, I'm sure I could use those 
orbital elements to DERIVE these data somehow, but that's beyond me... :>)

So my first question: what's the apparent velocity of the UPEs (i.e., what do 
the reports of "swift" meteors mean, exactly)? Second question: from what 
source can I find such details in future for OTHER non-IMO showers? Thanks!
