2013 06 18.7324 V. Lipunov (SAI MSU) reports the discovery by S. Shurpakov of a possible supernova (mag. 17.4) on 3 unfiltered survey images (limiting mag 19.4) taken on June 15.693 and 15.723, 06-15.723 UT (limit 19.5m) with the MASTER-Tunka robotic telescope (0.40-m f/2.5 reflector + 4Kx4K CCD). The new object is located at R.A. = 15h 49m 51.14s +60d 54m 48.1s (equinox 2000.0), which is 6.1" east and 1.6" south of the center of galaxy SDSS J154950.31+605449.7. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/154951.14605448.1.png (see also ATel #5147).
