Francis Leavenworth discovered NGC 480 = LM 2-304 in 1886 with the 26" Clark refractor at the Leander McCormick Observatory. His position is 25 sec of RA following PGC 4845 (described here). This galaxy satisfies the condition of being 40' S of NGC 481 which is the difference in dec given by Leavenworth and Corwin identifies PGC 4845 = NGC 480. Bigourdan failed to find NGC 480 at Leavenworth's position and the number is listed as nonexistent in the RNGC.

400/500mm - 17.5" (10/4/97): extremely faint and small, round, ~10" diameter. This marginal object required averted vision and the GSC finder chart to glimpse at 280x. Located 8' E of mag 7 SAO 147742 and nearly at the midpoint of two mag 12 stars 3.7' SW and 3.3' NE. Listed as nonexistent in RNGC and this identification of a Leavenworth discovery is uncertain (see notes).
