Heinrich d'Arrest discovered NGC 502 on 25 Sep 1862 with the 11-inch refractor at Copenhagen. His position (measured on 4 nights) matches UGC 922 = PGC 5034. The identifications of NGC 502 and NGC 505 are reversed in the MCG and should read NGC 502 = MCG +01-04-041 and NGC 505 = MCG +01-04-043.

400/500mm - 17.5" (10/17/87): fairly faint, small, small bright core, possible faint stellar nucleus. Member of the NGC 524 group.
