NGC 3982
18" (4/30/11): fairly bright, moderately large, round, 1.5' diameter. Broad concentration but no real zones, though the center is slightly brighter. Two mag 12/13 stars lie 3.5' S. Located 23' SW of NGC 3998 in a group of 6 galaxies. See Hubble image at http://hubblesite.org/newscenter/archive/releases/2010/36/image/a/
17.5" (5/2/92): bright, moderately large, elongated 4:3 N-S, 2.0'x1.5', broad concentration but does not have a well-defined core except for a faint stellar nucleus or very faint star superimposed at center. A wide pair (1.0' separation) of mag 11 and 12 stars lie 3.5' S. Forms a wide pair with NGC 3972 13' NW.
17.5" (4/18/98): 13th magnitude supernova SNGC 1998aq was an easy object within the outer halo.
