MASTER OT J160432.41+122840.7 - possible Supernova

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 16h 04m 32.41s +12d 28m 40.7s on 2014-02-06.12332 UT. The OT unfiltered magnitude is 17.5m (limit 19.2m). The OT is seen in 4 images. There is no minor planet at this place. We have reference image without OT on 2010-03-21.04197 UT with unfiltered magnitude limit 20.4m.

The OT is located 5" east and 11" north of the center of galaxy PGC 1410207 = SDSS J160432.04+122830.5 (z=0.0408). There is nothing but galaxy background at this position on SDSS color-combined image to limiting magnitude ~23.5. Spectral confirmation is required.
