V. Lipunov (SAI MSU) reports the discovery by S. Shurpakov of a possible supernova on the images from MASTER-Amur robotic telescope (0.40-m f/2.5 + 4Kx4K CCD) obtained on 2012 Oct. 19.738 and 19.769 UT. D. Denisenko and E. Gorbovskoy (SAI MSU) report that the object was present on MASTER-Amur images of 2012 Sep. 30, but was not detected then automatically as a transient. The following magnitudes (unfiltered with the red zero point) are reported: Sep. 30.642, 17.44+/-0.24; Sep. 30.674, 17.98+/-0.29; Oct. 19.738, 17.82+/-0.22; Oct. 19.769, 17.40+/-0.17. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/060401.40482508.9.png There is a faint object at the limit of digitized Palomar plates (~21m) which appears diffuse. Color combined (BRIR) DSS image is posted at http://master.sai.msu.ru/static/OT/J060401+482508-BRIR-5x5.jpg (5'x5' FOV).
