Édouard Stephan discovered NGC 2524 = St VIIIb-24, along with NGC 2528, on 22 Jan 1877 with the 31" reflector at the Marseille Observatory. His position is accurate and matches UGC 4234. Through a mix-up he placed NGC 2528 to the southeast of NGC 2524 instead of northwest. This error was caught and corrected by Esmiol in his 1916 re-reduction of Stephan's positions. See notes for NGC 2528.

400/500mm - 17.5" (2/24/90): fairly faint, fairly small, bright core, almost stellar nucleus, oval NW-SE. Forms a pair with NGC 2528 = UGC 4227 10' WNW.
