There is a bright star just past the south edge of this field, located at 00h 11m 22.4s +30d 26' 59" with a reliable Tycho-2 magnitude of 7.96+/-0.01. 2. Also known previously as var62 And. 3. Discovered as a dwarf nova by Antipin 1998, IBVS 4578 and called by him var62 And. Superhumps detected by Kato 2000, vsnet-alert 5274 with a period of 0.064 d proving this to be a SU UMa-type dwarf nova. Appears to vary considerably at minimum from V=18.7 to V=19.6.
