William Herschel discovered NGC 4237 = H II-11 = h1162 on 30 Dec 1783 (sweep 73) and recorded "another nebula about full 1/2° nf 6 Coma Ber. pL, very feeble, almost round, but not cometic. It is not a Messier, for being too feeble it could not be seen by an achromatic of 3 1/2 ft, which I suppose is the maximum of his light." No offsets in time and PD were measured, but the offset from 6 Com matches this galaxy. JH logged "B; L; lE; vgbM" and measured a fairly accurate position.

400/500mm - 17.5" (4/25/98): moderately bright and large, elongated 3:2 WNW-ESE, 1.5'x1.0'. Moderate concentration to a 30" irregular core which appears mottled. Located 15' NE of mag 6.3 SAO 100023. Poor transparency due to smoke.
