NGC 3309. See NGC 5298.
24" (3/28/17): fairly bright, moderately bright, slightly elongated, ~1.2'x1.0', contains a bright core that increases to a stellar nucleus. Highest surface brightness core of the main galaxies in the central region of the cluster and noticeably higher than NGC 3311 just 1.7' ESE. A mag 13.4 star is at the east edge (30" from center) and a mag 15 star is close WSW [48" from center].
13.1" (2/18/04 - Costa Rica): fairly bright, moderately large, well-concentrated with a bright 40" core, halo increases with averted from 1.2'x1.0' to 1.5'x1.2' oriented SW-NE. Forms a pair with NGC 3311 1.7' ESE in the core of AGC 1060.
13.1" (2/23/85): moderately bright, small, round. A mag 13.5 star is at the east edge. Forms a close pair with NGC 3311 1.7' E. Second of five in the core of AGC 1060.
