Lewis Swift discovered NGC 3555 = Sw. I-11, along with NGC 3551 = Sw. I-10, on 24 Aug 1883. There is nothing at his position, but exactly 1.0 min west is UGC 62035, the brightest member of the cluster. UGC, MCG and CGCG fail to label this galaxy as NGC 3555. This assignment implies NGC 3551 = CGCG 125-032, a faint double double system close southwest. See Corwin's notes for an alternate interpretation of the identifications.

400/500mm - 17.5" (4/15/99): brightest of trio with CGCG 125-032 (= NGC 3551) 1.4' SSW and CGCG 125-034. Appears very faint, small, round, 0.7' diameter. Located 9' NW of three mag 9 stars which form a shallow arc. This galaxy is the brightest in AGC 1177. CGCG 125-034 (identified as NGC 3555 in NED and LEDA) appeared extremely faint, very small, round, 15" diameter.

17.5" (3/12/94): faint, fairly small, round, 1.0' diameter, weak even concentration to brighter core and very small nucleus. A trio of mag 9 stars are in the field 8'-9' S including mag 8.9 SAO 81702 9.1' SE and mag 9.2 SAO 81700 8.7' SSE. Forms a close pair with NGC 3551 1.4' SSW.
