John Herschel discovered NGC 28 = h2310 on 28 Oct 1834 and described as "eF, preceding of 2. Requires attention, but no doubt remains." The 2nd object is h2311 = NGC 31. His position matches PGC 730. This galaxy is missing from ESO and RC3, but is included in the Southern Galaxy Catalogue (0007.9-5716) with the correct identification. The data in RC3 for NGC 28 refers to NGC 31 and PGC reverses the identifications of NGC 28 and 31. See Corwin's notes.

600/800mm - 30" (11/4/10 - Coonabarabran, 264x): moderately bright, fairly small, irregularly round, 30"x25", fairly high surface brightness, steadily increases to a very small bright core and stellar nucleus. Located in the core of AGC 2731 with NGC 31 1.8' E, NGC 25 4' SW and PGC 394784 2.4' SSE.
