Corwin's Notes
=====
NGC 3523 is H. II 904 from WH's problematic sweep 1096 of 2 April 1801; all
the positions in that sweep suffer from large, systematic errors. See NGC
3752 for more.
Steve's Notes
=====
NGC 3523
24" (5/25/14): at 280x appeared fairly faint or moderately bright, moderately large, irregularly round, 1' diameter, weak concentration to a slightly brighter core that seems offset center within the halo. Third in the KTG 34 triplet with NGC 3500 = UGC 6090 7' NW.
18" (3/30/05): fairly faint, moderately large, round, 1.2' diameter. Symmetrical appearance with a weak even concentration to the center but no defined core. NGC 3500 lies 7.2' NW.
17.5" (4/25/98): extremely faint, fairly small, round, 45" diameter, low even surface brightness. Collinear with two mag 11 stars 5' ESE and 9' ESE. Brightest in trio with NGC 3465 14.5' WNW and NGC 3500 7' NW. Observation severely hampered by poor transparency.
