Stephane Javelle discovered IC 528 = J. 2-631 on 12 Dec 1893 with the 30-inch refractor at the Nice Observatory. He recorded "pB, vS, R, mottled, Nucl =13m" and measured an accurate position.

400/500mm - 17.5" (4/5/97): faint, moderately large, elongated ~3:1 NNW-SSE, 1.4'x0.4'. Contains a brighter core with faint tapering extensions. View hampered by a mag 9 star (SAO 98393) just 1.8' NE. This galaxy is the brightest in HCG 36 and the only member viewed, though it lies in the foreground of the other members of the quartet.

900/1200mm - 48" (4/1/11): at 488x appeared bright, moderately large, elongated 5:2 NNW-SSE, 1.0'x0.4', sharply concentrated with a small, very bright core. Brightest of 5 close galaxies in HCG 36 with "C" 50" NW, "B" 1.1' NE, "D" 1.1' S and SDSS J090920.83+154747.3 25" W. Located 1.8' SE of mag 8.9 HD 78574, which hampers the view of HCG 36B.
