Contemporary Visual Observation(s) for NGC 3521
NGC 3521 = UGC 06150 = MCG +00-28-030 = CGCG 010-074 = PGC 33550 11 05 49.2 -00 02 02 V = 9.0; Size 11.0x5.1; SB = 13.2; PA = 163d 17.5": very bright, very large, elongated 5'x2' NNW-SSE. This is an impressive galaxy! Well-defined small bright oval core NNW-SSE, stellar nucleus. Appears mottled near the core and on the west side. Along the west side is a dust lane evident as a sharp light cut-off. The west side is somewhat fainter due to dust but extends beyond the dust lane. - by Steve Gottlieb
