Discovery of the Upsilon Andromedids (UAN, IAU #507)

During routine low-light level video observations with CAMS (Cameras for Allsky Meteor Surveillance) made from 2011 June 2 to August 7, a weak shower with a radiant near Upsilon Andromedae was discovered. In that same section of the sky, the Phi Piscids (PPS) were detected, listed as #372 in the IAU Working List of Meteor Showers. The Alpha Triangulids (ATR, IAU #414) and August Piscids (AUP, IAU #415) are activity from the same stream and should be removed from the list. Radiant and speed of the July Pegasids (JPE, IAU #175) match the Great Comet of 1771 (C/1771 A1) as well as earlier identified comet C/1979 Y1 Bradfield.
