Corwin's Notes

===== NGC 5782 was described by Swift as "eF, vS, E, * nr sf." His position is poor and lands on an empty patch of sky. 35 seconds preceding his position, though, there is a faint spindle that CGCG (076-094), MCG (+02-38-021), and RNGC all chose as the galaxy Swift saw. It fits his description, down to the star south-following -- except that there are two brighter stars closer to the galaxy north-preceding. Why didn't Swift mention them as well? There is, in fact, a better candidate for N5782. Steve Gottlieb points out that UGC 9602 and its fainter companion match exactly the revised position that Bigourdan provided in 1894 (and confirmed in 1899). Dreyer reported this position in the IC2 notes, and there is every reason to adopt U9602 as N5782. There is a star -- brighter than any of the three around the other galaxy -- within an arcminute of the nucleus of U9602. Also, the galaxy is significantly brighter, and has a higher surface brightness, than CGCG 076-094. The companion is nearly in contact with U9602, and would probably appear as part of it in a smaller telescope, making it appear "extended," just as Swift described it.

Steve's Notes

===== NGC 5782 17.5" (6/3/00): fairly faint, small, round, 0.5' diameter, mild even concentration to center. Forms a close pair with MCG +02-38-023 just 52" NNE of center. The RNGC, CGCG, MCG, PGC and NED misidentify NGC 5782 = MCG +2-38-21 = CGCG 76-94.
