Wilhelm Tempel discovered NGC 2636 = T IX-8 on 27 Jul 1883, along with NGC 2646, with the 11" refractor at the Arcetri Observatory near Florence. His description reads "small, followed by two stars 11-12m close to the same parallel." Tempel's position is 1 degree north of UGC 4583 = PGC 24747 and the two stars are ~5' following. This misprint was corrected by Dreyer in the NGC notes section.

400/500mm - 17.5" (3/20/93): fairly faint, very small, round, small bright core, well-defined halo. Located 5' W of a pair of mag 10/11 with a separation 1.2'. Also located 12' SW of mag 7.7 SAO 6661. The NGC 2634 NGC 2634A pair lies 17' N, NGC 2646 15' SE and IC 2389 8' SSW.
