A possible supernova of magnitude about R = 13 was discovered by J. Skvarc on four 60 s CCD images taken with a 0.60-m f/3.3 Cichocki telescope from the Crni Vrh Observatory. The object is at R.A. = 10h43m53s.72, Decl. = +11d40'17".7 (equinox J2000), which is 60" W and 115" S from the center of M95. Nothing is visible on this location in our archive images from 2005-04-25, 2005-05-01, 2006-05-04, 2008-11-22, 2010-02-13, 2010-02-24 and 2012-02-15 nor in DSS image archives. We note that this object is only 3.3 arc seconds from the X-ray source [SYT2006] s8 listed in the paper http://cdsbib.u-strasbg.fr/cgi-bin/cdsbib?2006ApJ...647.1030S by Swartz, Yukita, Tennant, Soria and Ghosh. The image composed of all 4 discovery images can be found at http://www.observatorij.org/vstars/PSN20120317/PSNJ10435372+1140177.jpg. We note that Mars is presently only about half degree from this object and this is also causing the four diffraction spikes on the composite image.
