Wilhelm Tempel discovered NGC 2460 = T VI-3 on 11 Aug 1882 and recorded a "small nebula II-III class, round, with star in the middle; repeatedly seen." His position is just 7 tsec E and 1.5' N of UGC 4097.
300/350mm - 13.1" (1/11/86): moderately bright, fairly small, bright core, diffuse halo, slightly elongated SW-NE. Forms a (probably interacting) pair with IC 2209 5' SW. Using averted vision the IC appeared very faint, diffuse, small, weak concentration.
