Royal Frost discovered IC 3483 = F. 955, along with IC 3481, on a plate taken 10 May 1904 at Harvard's Arequipa Observatory in Peru. He noted, "bM, magn 14."

600/800mm - 24" (6/4/16): faint to fairly faint, elongated 5:2 N-S, 36"x15", low surface brightness. Situated just southwest of a mag 10 star. Third in a linear trio (Zwicky's System or Triplet) with IC 3481A 4.1 NW and IC 3481 5.5' NW. The latter two galaxy are interacting, but IC 3483 lies well in the foreground.
