Steve's Notes
=====
NGC 5557
18" (5/3/08): at 280x appeared bright, moderately large, round. Contains a bright, 40" core and a sharply concentrated 10" intense nucleus with a bright stellar point at the center. The outer halo is much fainter and extends slightly E-W, ~1.5'x1.3'. A mag 10 star lies 4.8' NW. NGC 5544/5545 (Arp 199) lies 17' WNW.
17.5" (3/23/85): bright, fairly small, small bright core dominates. A very faint star is involved at SE side. The NGC 5544/NGC 5545 pair lies 16' NW and the thin edge-on NGC 5529 is 38' WSW.
8" (4/24/82): fairly faint, bright core.
