NGC 3656
48" (4/6/13): bright, moderately large, irregularly round, ~1.3'x1.0', large very bright core but no distinct nucleus. A mag 12.7 star is just off the west edge of a large, diffuse halo. A dust lane or absorption patch is evident on the north side as a region of lower surface brightness.
MCG +09-19-64, a merging companion, is attached at the southern edge of the halo [40" S of center]. It appeared faint, fairly small, low surface brightness, slightly elongated E-W, 20"x15". PGC 2452556, 2.3' ENE, was a fairly faint, fairly small, roundish glow, 15" diameter, with a brighter core.
18" (5/30/03): moderately bright, round, fairly small, 0.8' diameter, fairly weak concentration with a brighter core. A mag 12 star is just off the west side, 45" from center.
