Steve's Notes

===== NGC 5490 18" (5/3/08): bright, irregularly round, moderately large, ~1.0'x0.8' N-S, sharply concentrated with a very bright 20" core and stellar nucleus. Brightest in a group including NGC 5490B = MCG +03-36-067 1.6' ENE, IC 982 9' N and NGC 5490C 4.8' NNE. NGC5490B appeared extremely faint and small, round, 10" diameter, required averted vision to glimpse. NGC 5490C = Arp 79 appeared very faint, fairly small, 25" diameter, irregularly round, low even surface brightness. 17.5" (6/23/01): moderately bright, moderately large, slightly elongated N-S, bright core, stellar nucleus. Brightest in a group with MCG +03-36-064 2.9' NNW and NGC 5490C = Arp 79 located 4.7' NE. A close companion, MCG +03-36-067, off the east side not seen. The group is located two degrees SW of Arcturus! 17.5" (5/23/98): fairly faint, fairly small, round, 1.0' diameter, small bright core. Brightest in a small group with several faint nearby companions (not seen), IC 983 11' N and IC 982 9' N.
