William Herschel discovered NGC 4527 = H II-37 = h1330 on 23 Feb 1784 (sweep 158) and recorded "pB, of an extended shape, from np to sf and mbM than at the ends." His orientation should read "sp to nf". On sweep 143, JH logged "pB; pL; gmbM; E in pos 30° nf to sp."

400/500mm - 17.5" (3/24/90): fairly bright, very large, very elongated WSW-ENE, prominent core, small bright nucleus. NGC 4536 is 30' SSE with mag 8.8 SAO 119473 and mag 8.6 SAO 119474 near the midpoint. NGC 4533, a fainter galaxy, also lies 20' S.

600/800mm - 24" (5/20/17): at 200x; bright; very large; very elongated ~4:1 WSW-ENE, ~4'x1',well concentrated with a very bright elongated core that contains a fairly intense nucleus. Appears to brighten slightly and curl south on the western end and spread out and curl a bit north on the eastern ends, like the beginning of spiral arms (verified later on the DSS). IC 3474 lies 23' due east.
