Pavel Balanutsa and Vladimir Lipunov, Sternberg Astronomical Institute, on behalf of the MASTER robotic-telescopes network, report the discovery of an apparent supernova (mag 13.6) on a 60-s unfiltered CCD image (limiting mag 16.2 with an Apogee AltaU16m camera) taken on 2009 Dec. 22.901 UT at Blagoveschensk. Images (limiting magnitudes V = 17.8, R = 18.1) taken at Kislovodsk on Dec. 31.1 yield V = 13.1 and R = 13.5 for the new object. SN 2009nr is located at R.A. = 13:10:58.95, Decl. = +11:29:29.3 (equinox 2000.0), which is 36" east and 50" north of the center of the galaxy UGC 8255. Nothing is visible at this position on twenty reference images taken over the past six years with a robotic telescope near Moscow, including one taken on 2008 Apr. 2 (limiting red mag 17.5).
