Andrew Ainslie Common discovered NGC 3360 in 1880 with his 36-inch silvered-glass reflector. His description reads "A F[aint] pair, f one brighter." There is nothing at his position, but 10' north is MCG -02-28-003 = PGC 32026, which forms a pair with NGC 3361 = MCG -02-28-004 about 3.8' NE.

Herbert Howe's published position in his series of MN articles matches MCG -02-28-003, although it is incorrect in the IC Notes.

400/500mm - 17.5" (4/21/01): faint, small, elongated 4:3 WSW-ENE, 0.8'x0.6'. Low, nearly even surface brightness. Forms a pair with NGC 3360 3.8' NE.
