NGC 4477
24" (5/29/14): very bright, fairly large, round, 2.0' diameter, sharply concentrated with an intensely bright core and stellar nucleus. Forms a pair with NGC 4479 5.3' SE.
18" (6/12/10): very bright, fairly large, slightly elongated SSW-NNE, 2.5'x2.0'. The outer halo is very weakly concentrated and then suddenly increases to an intense 40"x20" core. At 275x the core appears lively or mottled and increases to a stellar nucleus. Forms a pair with NGC 4479 5.3' SE.
17.5" (4/25/87): fairly bright, moderately large, slightly elongated ~N-S, bright core, stellar nucleus. Forms a pair with NGC 4479 5.5' SE and NGC 4473 lies 12' SSW.
13" (5/14/83): bright, slightly elongated N-S, small bright nucleus, NGC 4479 5.5' SE.
