Lewis Swift discovered NGC 5920 = Sw. VI-78, along with NGC 5919, on 30 Mar 1887 and recorded "eeF; pS; lE; ee diff; sf of 2 [with NGC 5919]." His position matches UGC 9822 though UGC doesn't label this galaxy as N5920. NGC 5920 is the brightest in a group (MKW 3s) of about 10 galaxies. See notes on NGC 5919.

400/500mm - 17.5" (7/9/94): very faint, fairly small, round, 0.8' diameter, very low surface brightness with a very slight concentration. Located between a mag 14 star off NW edge 1.1' from center and a mag 15 star just off the SE edge. Two mag 10/11 stars lie 4.5' SSW and 3.3' SSW, respectively. This galaxy is the brightest in cluster AGC 2063 with NGC 5919 3' W.

600/800mm - 24" (6/23/17): at 375x; faint to fairly faint, moderately large, slightly elongated ~5:4, ~40"x32". Exhibited a broad weak concentration with a slight brighter, but ill-defined core. Situated 10' SW of mag 8.7 HD 136797. NGC 5920 is the brightest of at least 7 galaxies within 5.4'!

PGC 54838, situated 1.6' N, appeared faint (V = 15.2), small, round, 12"-15" diameter, 15th mag stars are 0.8' SSW and 0.8' NNW.
