Lewis Swift discovered NGC 155 = Sw. IV-2 = LM 1-6 on 1 Sep 1886 with the 16" refractor at Warner Observatory. His position is 10 sec of RA west of MCG -02-02-055 = PGC 2076. Frank Muller also found the galaxy in 1886 (sometime before Oct 12th) with the 26" Leander McCormick refractor and reported "mag 13.0, S, R, bsp, *12 in PA 90° at 3.2' separation." Bigourdan measured an accurate micrometric position on 21 Oct 1890 as well as Howe at Denver near the end of the century.

400/500mm - 17.5" (9/17/88): fairly faint, very small, oval 4:3 N-S, bright core.
