The nucleus of the western component (PGC 215034) is just 25" W. It was moderately bright but appeared stellar. At 697x, a very low surface brightness, very small halo was visible, but the tidal plume or jet extending southwest was not seen.

Stephane Javelle discovered IC 803 = J. 1-220 on 25 Apr 1892 with the 30-inch f/23 refractor at Nice, France. His position is accurate.

900/1200mm - 48" (4/19/15): at 488x and 697x; the core of the eastern component of this interacting double system appeared fairly faint, small, round. A very faint, thin spike (tidal plume or jet) was visible extending ~15" SE. Occasionally a second, very faint stubby tidal tail extended ~10" north-northwest . The entire length of this chaotic galaxy was ~30".
