William Herschel discovered NGC 5376 = H I-238 on 24 Apr 1789 (sweep 926) and recorded "cB, pL, vgmbM, iR." CH's reduced position is less than 2' southeast of UGC 8852. It was recorded again on 19 Mar 1790 in sweep 953 as II-844 (accurately placed), but he didn't realize the equivalence, so NGC 5376 received two H and GC designations that were combined in the NGC.

200/250mm - 8" (4/24/82): faint, small, slightly elongated. NGC 5389 lies 15.5' NNE.

400/500mm - 17.5" (5/27/95): moderately bright, elongated 3:2 ~E-W, 1.5'x1.0', broad weak concentration with no distinct core. The NGC 5379/5389 pair lies 15' NNE.
