William Herschel discovered NGC 5928 = H II-874 = h1923 on 24 May 1791 (sweep 1006) and recorded "pB, pL, vgmbM, iR." JH made the single observation "pB; S; R; psbM; a * 7.8m, 6' north." and measured a fairly accurate position. In the IC 1 Notes section, Dreyer mentions this galaxy is possibly M102.
400/500mm - 17.5" (5/30/92): fairly faint, fairly small, elongated 3:2 ~E-W, small bright core. Located 6.0' SSW of mag 7.8 SAO 101554. Forms a pair with UGC 9841 14' NNW.
