Albert Marth discovered NGC 3477 = m 214 on 25 Mar 1865 and noted "eeF, eS, stell." His position is 4' north of CGCG 066-074 = PGC 32997, the same offset he made with nearby NGC 3476.

400/500mm - 17.5" (3/22/96): extremely faint, very small, elongated 2:1 SW-NE (difficult to determine PA as requires averted vision to glimpse). A faint pair of mag 15 stars lies 2.3' N. At the SE edge of the 220x field is a matched pair of mag 9.5 stars at 16" separation. Forms a pair with brighter NGC 3476 3.7' NNW.
