Corwin's Notes
=====
NGC 3801. Steve Gottlieb suggests that WH saw this brighter of the pair --
NGC 3802 is the fainter -- twice, so that H III 30 = H II 161 = h 939 = GC
2490 = NGC 3801. This leaves JH as the sole discoverer of NGC 3802. See also
NGC 3807 where this figures in observations by LdR.
Steve's Notes
=====
NGC 3801
48" (4/2/11): the brightest of 6 galaxies in a 15' group that is stretched out in a SW to NE orientation. At 375x appeared very bright, very large, elongated 3:2 WNW-ESE, ~2.5'x1.7', sharply concentrated with a very bright core and much fainter outer halo. There is some ill-defined structure in the halo, either due to dust, spiral arms or both. NGC 3802 is 2.3' N, MCG +03-30-035 is 3.4' SW, NGC 3803 is 4.5' N, NGC 3790 is 7' WSW and NGC 3806 is 8' NE. MCG +03-30-035 (B = 16.6) appeared fairly faint, moderately large, very elongated 4:1 SW-NE, ~40"x10". A mag 11.5 star is 2.4' preceding.
18" (5/12/07): moderately bright, fairly large but moderately low surface brightness, elongated 5:3 NW-SE, broad concentration with a brighter core that increases to a small, brighter nucleus. Brightest in a group including NGC 3790 7' W and NGC 3802 2.3' N.
17.5" (4/1/95): brightest in a group. Fairly faint, fairly small, elongated 3:2 NW-SE, 1.2'x0.8', broad concentration to a brighter core. Forms a close pair with NGC 3802 2.3' NNE. Also in the field are NGC 3790 7.0' WSW and NGC 3806 8.1' NE. Located 7' WNW of mag 8.7 SAO 99729.
