V. Lipunov (SAI MSU) reports the discovery by P. Balanutsa of a possible supernova (magnitude 17.8) on the unfiltered images (60-sec exposures) from MASTER-Amur robotic telescope (0.40-m f/2.5 + 4Kx4K CCD) taken on 2012 Oct. 21.547 and 21.579 UT. Nothing is visible on the unfiltered image from the same telescope of 2012 Oct. 10.665 UT with magnitude limit 19.0m. There is a faint diffuse object within 1" of the PSN at the limit of digitized Palomar plates (~21m).
