Denis Denisenko and V. Lipunov, Sternberg Astronomical Institute (SAI), Lomonosov Moscow State University, reports the discovery by P. Balanutsa of an apparent supernova (magnitude 16.5) on two 60-s unfiltered survey images taken by the MASTER-Amur robotic telescope (0.40-m f/2.5 reflector) on Oct. 25.844 and 25.877 UT. The new object is located at R.A. = 13:14:47.05, Decl. = +54:05:05.5 (equinox 2000.0), which is 4".4 east and 9".1 south of the core of the galaxy PGC 3087098 (= SDSS J131446.51+540514.8, with z = 0.03316). D. Denisenko and E. Gorbovskoy (SAI) add that nothing is visible at this position on unfiltered images from the identical MASTER-Tunka telescope taken on 2012 May 5.735 UT (limiting mag 18.8) or on digitized Palomar Sky Survey plates to limiting magnitude about 21 and on a Sloan Digital Sky Survey color image to limiting mag about 23. Relevant images are posted at website URL http://master.sai.msu.ru/static/OT/PSNJ131447+540505-DSS-SDSS.jpg. The variable was designated PSN J13144705+5405055 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012ge based on the spectroscopic confirmation reported below. Joseph Brimacombe (Cairns, Australia) reports red mag 18.0 and position end figures 47s.18, 05".2 for 2012ge from images taken on Nov. 2.494; he has posted imagery of 2012ge at website URL http://www.flickr.com/photos/43846774@N02/8152997448/.
