Corwin's Notes
=====
NGC 523 = NGC 537, which see. Also see NGC 5765 for a note on objects noted
as double by WH or JH yet given just a single position.
Steve's Notes
=====
NGC 523
24" (11/24/14): fairly bright, moderately bright, very elongated 7:2 ~E-W, ~1.1'x0.3'. This disrupted galaxy (or merger) appeared very asymmetric, widening a bit at the east end and tapering slightly to the west. A small, relatively bright knot (HII complex or core of companion?), ~10" diameter, is at the east end. An easily visible mag 14-14.5 star is embedded at the west end. The main body, which extends ~40" from the knot to the star, is fairly thin and only very weakly brighter in the center. With careful viewing, a very faint narrow plume extends west of the main glow.
13.1" (12/22/84): moderately bright, thin edge-on 4:1 ~E-W. Located north of the NGC 483-517 cluster.
