Vladimir Lipunov, Sternberg Astronomical Institute, reports the discovery by P. Balanutsa of the discovery of an apparent supernova (mag 18.5) on unfiltered CCD images (limiting mag 19.4-19.5) taken on Sept. 30.87 and 30.90 UT in the course of the MASTER Net project (http://observ.pereplet.ru/) at the MASTER-Tunka observatory. The new object is located at R.A. = 3:57:40.87, Decl. = +10d09m55s.2 (equinox 2000.0 presumed), which is 5".3 east and 17".8 south of the center of the presumed host galaxy (which they identify as PGC 1375631). Nothing is visible at this position on an unfiltered image taken at the MASTER-Kislovodsk observatory on 2010 Sept. 18.96 (limiting mag 19.6). An image of the variable, which is designated SN 2011ha based on the spectroscopic confirmation reported below, is posted at the following website URL: http://observ.pereplet.ru/images/SN110830/PSN_PGC1375631/S1.png.
