William Herschel discovered NGC 5526 = H III-804 = h1763 on 17 Apr 1789 (sweep 924) and noted "cF, S, E." His position and description matches UGC 9115. He observed the galaxy again on 17 Mar 1790 (sweep 948), recorded it again as III-835 at nearly the same position (CH's reduction). JH combined the two H-designations in the GC.
400/500mm - 17.5" (5/27/95): very faint, thin edge-on 6:1 NW-SE, 1.2'x0.2'. Appears as a low surface brightness sliver with no concentration. A mag 14 star is 0.8' NNE of center.
600/800mm - 24" (6/3/19): at 322x; moderately bright and large, very nice thin edge-on 6:1 NW-SE, ~1.2'x0.2', brighter elongated core. A mag 14.3 star is 40" N.
Forms a close pair with PGC 50803, just 30" SW. The apparent companion appeared extremely faint, very small, round, at most 10" diameter. Required averted to glimpse but repeatable in same position perhaps 20% of the time.
24" (7/12/18): at 375x; faint, moderately large, very thin edge-on 7:1 NW-SE, ~70"x10", fairly low nearly even surface brightness with only a slightly brighter core. A mag 14.3 star is 40" NNE of center.
MCG +10-20-084 = PGC 50803 forms a very close pair just off the west side, 0.5' from center. It appeared very faint, round, 12" diameter. This apparent companion lies far in the background (5.7 times the distance) at 540 million l.y.
