Stephane Javelle discovered IC 4371 = J. 3-1291, along with IC 4369 and 4370, on 3 Jul 1896. His position is an exact match with Hickson 70B = PGC 50140. Despite the good IC position, UGC, CGCG, MCG, PGC and HyperLEDA misidentify PGC 50140 as IC 4369.

400/500mm - 17.5" (4/18/98): the largest member of HCG 70 group appears faint, fairly small, elongated 3:2 SW-NE, 40"x25". Situated midway between the HCG 70A/D pair 2' N and a mag 10-11 2' S.

900/1200mm - 48" (5/12/18): at 488x; bright to very bright, moderately large, slightly elongated SW-NE, ~0.6'x0.4'. A mag 11 star is 2.3' due south. HCG 70A (often misidentified as IC 4371) is 1.8' due north.
