Contemporary Visual Observation(s) for NGC 4244 | |||
NGC 4244 = UGC 07322 = MCG +06-27-045 = CGCG 187-035 = FGC 1402 = PGC 39422 12 17 29.4 +37 48 24 V = 10.4; Size 16.6x1.9; Surf Br = 14.0; PA = 48d 18" (6/4/05): beautiful, extremely large ray extends at least 3/4 across the 20' field, ~15'x1' SW-NE. Broadly concentrated, but does not contain a well-defined core or nucleus, though bulges very slightly at the center. The surface brightness is fairly low and only varies gradually over the entire length, but has an grainy texture. A mag 13.5 star is near the NE end. 13.1" (4/12/86): fairly bright, extremely large edge-on about 10:1 SW- NE. Extends to 15'-20' diameter (fades at the ends of the extensions). Appears as a narrow ray with only a weakly concentrated core. | |||
