Frank Muller discovered NGC 143 = LM 2-283, along with NGCs 142 and 144, in 1886 with the 26" refractor at Leander McCormick Observatory. His rough position is a reasonable match with ESO 473-022 = PGC 1911. Herbert Howe measured an accurate position in 1899-00 using the 20" refractor at Chamberlin Observatory (repeated in the IC 2 notes).

400/500mm - 17.5" (10/8/88): second of three with NGC 142 and NGC 144. Extremely faint, small, oval SSW-NNE. Located 3' NNE of NGC 142.
