Wilhelm Tempel discovered NGC 4360 = T I-43 on 22 Mar 1878. His micrometric position in discovery list V (+4.87 sec of RA and -47" dec from HD 107953) matches UGC 7484. Édouard Stephan independently found NGC 4360, as well as 4316, on 1 Apr 1884 and reported it as new in his 13th discovery list (#69). His position was accurate.

400/500mm - 17.5" (3/24/90): fairly faint, very small, slightly elongated, small bright core. Located 1.3' SE of a mag 10 star. Forms a pair with IC 3274 2' SW. The companion (identified often as NGC 4360B) appeared very faint, extremely small, round, low surface brightness, just non-stellar.
