Steve's Notes

===== NGC 2648 48" (2/21/12): very bright large spiral, elongated ~5:2 NNW-SSE, ~2.4'x0.9'. Contains a large, very bright core that increases to a stellar nucleus. Forms an interacting pair (Arp 89) with MCG +02-22-006 2.4' SE of center. NGC 2648 has an asymmetric appearance with the south-southeast arm stretched into a faint tidal tail. The brighter portion of the arm extends south-southeast of the core (in the direction of the major axis), but a faint thinner extension curves and sweeps east, fading out just before connecting with MCG +02-22-006. A mag 11 star is 1.9' E. The companion appeared moderately bright, edge-on 5:1 WNW-ESE, 1.0'x0.2', sharply concentrated with a very small, bright nucleus. The system was classified by Arp under "spiral with a large high surface-brightness companion on arms". 24" (4/28/14): moderately to fairly bright, moderately large, elongated 5:2 NW-SE, sharply concentrated with a very bright core, 1.5'x0.6'. A mag 11 star lies 1.9' E of center. Forms a pair (Arp 89) with edge-on MCG +02-22-006 2.4' SE. The companion appeared very faint, small, elongated 5:2 WNW-ESE, ~25"x10", low even surface brightness. 17.5" (2/1/92): moderately bright, fairly small, elongated 5:2 NW-SE, small very bright core. Located 1.9' W of a mag 10.5 star.
