Lewis Swift discovered NGC 992 = Sw. IV-10 on 6 Sep 1886 with the 16" refractor at Warner Observatory. His RA was 8 seconds too small but his description ("cE, * nr S") matches. Bigourdan added the note "it passes 7 seconds before the NGC position" in the correction list in his 1891 Comptes Rendus paper, but that should read "7 seconds after" (so the correction is nearly 15 seconds off). Kobold measured an accurate position in 1902 with the 18" refractor at the Strasbourg Observatory (published in 1907).

400/500mm - 17.5" (1/20/90): fairly faint, small, elongated N-S, very faint extensions. Located 4.3' SSW of mag 8.5 SAO 75477. A mag 12.5 star is 1.4' SE of center.
