Vladimir Lipunov reports the discovery by Vladislav Shumkov of a possible supernova with unfiltered magnitude 17.2 on the survey images (180-s exposures, limiting magnitude 19.9m) obtained by MASTER-Kislovodsk robotic telescope (0.40-m f/2.5 reflector + 4Kx4K CCD) on 2014 Aug. 28.0045 UT. The new object is located at the following position (J2000.0): R.A. = 03h08m31s.74, Decl. = +14o25'30".3 which is 1" east and 7" south of the center of galaxy PGC 1457807. D. Denisenko and E. Gorbovskoy report that nothing but galaxy background is present at this position on the images taken by the same telescope on 2011 Jan. 11.682 UT to the unfiltered magnitude limit 22.1. The discovery and reference images by MASTER are available at http://master.sai.msu.ru/static/OT/030831.74142530.3.png (see also ATel #6434, http://www.astronomerstelegram.org/?read=6434)
