George Johnstone Stoney, Lord Rosse's assistant, discovered IC 464, along with IC 458, 459, 461 on 31 Jan 1851. Lewis Swift probably found this galaxy again on 14 Sep 1888 (list VIII-45). Kobold measured an accurate position on 18 Jan 1893.

400/500mm - 17.5" (1/20/90): faint, small, oval SW-NE. Located 2.5' SSW of NGC 2340 in a group with IC 458 5.0' WSW and IC 465 8.1' NE.

600/800mm - 24" (2/13/18): at 200x and 375x; fairly faint, fairly small, oval 2:1 SW-NE, 50"x25", bright core. Located 2.4' SSW of NGC 2340 in a rich galaxy group. IC 463 is 1.3' SSW.
