NGC/IC Project Restoration Effort

===== NGC 4646. Like NGC 4644, Dreyer found a companion, UGC 7905, to this galaxy, too. The story is in the "notngc" files.

===== NGC 4646 24" (5/30/16): at 225x; moderately bright, fairly small, elongated 2:1 SSW-NNE, 0.6'x0.3', bright irregular core seems knotty. A mag 14.8 star is very close to the northeast edge. Four collinear mag 13-14.5 stars extending to the northwest begins 2.5' W. UGC 7905, a disturbed, interacting system with tidal tails extending from both galaxies, lies 8.5' ENE. The pair is oriented SSW to NNE with centers separated by 35". At 225x, the southwest member (Mrk 220) appeared fairly faint, small, high surface brightness, roundish, 18" diameter. The northeast component (Mrk 221) appeared faint, fairly small, 18", low surface brightness. Only the central region was seen and I missed the tidal tail extending to the north and east. 18" (6/28/03): fairly faint, small, elongated 2:1 SSW-NNE, 0.5'x0.25', stellar nucleus. There appears to be a faint star at the NE tip (verified on DSS). A striking line of four mag 13-14 stars (total length 2.8') is close NW.
