The new object, which was confirmed at mag approximately 15.4 in an image taken with the 'PROMPT 5' telescope on Jan. 7.26, is located at R.A. = 11:17:54.88 ± 0".3, Decl. = -2:05:45.2 ± 0".3 (equinox 2000.0), which is about 1".4 west and 14".4 south of the center of the galaxy UGC 6311. Nothing is visible at this position on archival images taken on 2010 May 4.05 and Dec. 17.30 (limiting mag 18.0).
