V. Lipunov (SAI MSU) reports the discovery by S. Shurpakov of a possible supernova (mag. 19.1) on two unfiltered survey images (limiting mag 19.5) taken on Jan. 16.988 and 16.956 UT with the MASTER-Kislovodsk robotic telescope (0.40-m f/2.5 reflector + 4Kx4K CCD). The new object is located at R.A. = 12h51m51s.70, Decl. = +47o16'18".0 (equinox 2000.0). The OT unfiltered magnitude is 19.1m (limit 19.5m). The OT is seen in 2 images. There is no minor planet at this place. We have reference image without OT on 2012-03-02.89241 UT with unfiltered magnitude limit 19.7m. There is SDSS galaxy J125152.01+471620.0 with 3.8 arcsec offset. Spectral observations are required.
