R.J. Mitchell discovered NGC 5527 on 19 Apr 1855 with LdR's 72" during an observation of the NGC 5529 field. This nova was described as "another vF about 15' np [of NGC 5529]." CGCG 191-067 = PGC 50868 is a good match with this description (the actual separation is 17') Most galaxy catalogues misidentify CGCG 191-067 as NGC 5524 (this was also Bigourdan's interpretation). But NGC 5524 derives from Mitchell's description "another eeF about 6' preceding and 1' north of this last [NGC 5527]." Corwin identifies NGC 5524 as an unequal double star, located 6' preceding and 1' south of NGC 5527.

RNGC, PGC, SIMBAD and WikiSky misidentify MCG +06-31-085a as NGC 5527. MCG +06-31-085a is an extremely low surface brightness galaxy 0.3 min of RA west and 2' south of NGC 5529. NED and HyperLeda correctly identify PGC 50868 as NGC 5527. Finally, Rosse also mentions a "vF neb sf NGC 5529], and in this direction is CGCG 191-071 (see observing notes). Unfortunately this object didn't receive a NGC number, probably due to the lack of offset or a sketch.

400/500mm - 17.5" (5/27/95): very faint, small, round, 30" diameter. No concentration although appears asymmetric and possibly brighter on the west side (or an extremely faint star superimposed). Located 17' NW of NGC 5529. This galaxy is identified as NGC 5524 in modern catalogues.
