Forms a pair with UGCA 180, just 3.5' SE. It appeared as an extremely faint glow, seems moderately large but the surface brightness was too low to see any structure.

Lewis Swift discovered IC 2507 = Sw. XI-96 on 19 Feb 1898 and recorded "eF; S; R; vF * close nf; pB * near sp." Swift's position is 32 seconds of RA west of ESO 434-031. In his series of Monthly Notices articles, Howe reported (Nov. 1900) the "pB * near sp" is actually 2.4' N and 6 seconds of RA west and he also measured an accurate position for the galaxy. Delisle Stewart picked up the galaxy in 1900 on a Harvard plate and described it as "eB, cL, E at 55°."

600/800mm - 24" (4/13/18): at 225x; fairly faint, moderately large, elongated 5:3 SW-NE, ~45"x27", irregular surface brightness. A very faint 16th mag star is superimposed on the south side, and there seemed to be a knot(s) or clumpiness on the SW end. Two mag 13.8 and 15.2 stars are just off the NE end. A mag 10.3 star is 2.7' NW.
