Édouard Stephan discovered NGC 662 = St XIII-12 on 22 Nov 1884 with the 31" reflector at the Marseille Observatory and noted "F, S, R, rather marked central condensation". His position is accurate.

400/500mm - 17.5" (11/27/92): fairly faint, very small, fairly high even surface brightness, elongated 3:2 ~N-S. Located 3' ENE of mag 6.9 SAO 10617, which hampers viewing.
