John Herschel discovered NGC 37 = h2312 on 2 Oct 1836 and recorded as "extremely faint, small, round.". His position matches ESO 149-022 = PGC 801, though ESO doesn't label their catalogue entry as NGC 37.

600/800mm - 30" (11/4/10 - Coonabarabran, 264x): fairly faint, fairly small, elongated 3:2 SSW-NNE, 0.6'x0.4'. Sharply concentrated with a very bright compact core, surrounded by a low surface brightness halo. A mag 15 star lies 0.8' E. 2MASX J00111972-5657065 = LEDA 95382, a very compact galaxy, is just off the NW side. This member of AGC 2731 is located 6.3' ENE of NGC 31. A couple of faint members lie 2.5' NNE (2MASX J00112633-5655018) and 3' NE (2MASX J00114159-5655469).
