This galaxy is identified as IC 2002 in UGC, MCG, CGCG and RC3 due to a poor declination by Marth. RNGC reverses the sign of the declination.

Stephane Javelle found IC 2002 = J. 3-983 on 21 Dec 1903 and described "Weak, elongated in the direction of the meridian [N-S], a star is north, very weakly condensed." His position matches UGC 2898 = PGC 14065. This galaxy was probably discovered by Albert Marth on 5 Oct 1864. His position for m 93 (later NGC 1474) is 8' S of this galaxy, but this is the only nearby galaxy he could have picked up. UGC, MCG, CGCG and RC3 only use the IC designation as the position is unambiguous, though online catalogues (NED, HyperLEDA and SIMBAD) equate NGC 1474 = IC 2002. In addition, PGC and RNGC reversed the sign of the declination of NGC 1474 (repeated in Roger Sinnott's NGC 2000.0 and amateur software including Megastar). See my RNGC Corrections #6 and Corwin's notes.

400/500mm - 17.5" (2/11/96): faint, fairly small, round, 40" diameter, weak concentration to a slightly brighter 15" core. A mag 13.5 star is just 1.0' N of center. Located 12' WSW of mag 9 SAO 93675.
