From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 4051 NGC 4051 = UGC 07030 = MCG +08-22-059 = CGCG 243-038 = PGC 38068 12 03 09.6 +44 31 53 V = 10.2; Size 5.2x3.9; SB = 13.3; PA = 135d 17.5": fairly bright, large, ~4.0'x2.5' NW-SE. Nearly extends to a mag 11 star 2.2' W. Very bright, very small core increasing to a bright stellar nucleus. The galaxy shows signs of spiral structure and there appears to be a short outer spiral arm attached at the SE end hooking N separated by a slightly darker region between the main body (verified on photo). NGC position is accurate. The RA in the RNGC is 1.0 tmin too far W. - by Steve Gottlieb |
