William Herschel discovered NGC 4124 = H I-33 = H II-60 = h1094 on 15 Mar 1784 (sweep 174) and logged II-60 as "F, S, r." Caroline's reduced position is 2' northeast of UGC 7117. He logged it again as I-33 exactly a month later as "B, L, mE, mbM, r." A note was added "by description not the same as [II-60]. Nevertheless, John Herschel combined both (correctly) H-designations in the GC. John Herschel made an early observation on 11 Apr 1825 (sweep 3) and noted it was "extended in a north-preceding directions towards a star, 30" diameter."

William Herschel probably discovered this galaxy earlier on 18 Jan 1784 and listed it as H. II-14 (later NGC 4119). See notes on this number. Finally Schwassmann's Sn. 124 = IC 3011, found on a Heidelberg plate on 23 Feb 1900, is an exact match. So, NGC 3124 = NGC 4119 = IC 3011.

400/500mm - 17.5" (5/14/88): bright, fairly large, elongated WNW-ESE, bright elongated core.

17.5" (5/10/86): fairly bright, moderately large, attractive system, very elongated 3:1 WNW-ESE, elongated large bright core.
