MASTER OT J012612.90+114027.7 - PSN in PGC 1397065

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 01h 26m 12.90s +11d 40m 27.7s on 2014-12-09.77363 UT. The OT unfiltered magnitude is 18.3m (limit 19.7m). The OT is seen in 4 images. There is no minor planet at this place. We have reference image without OT on 2014-09-03.02838 UT with unfiltered magnitude limit 20.3m.

The OT is located 12" west and 6" north of the center of galaxy PGC 1397065 = 2MASX J01261370+1140218 = SDSS J012613.70+114021.3 (g=16.04 r=15.07 i=14.58) with unknown redshift. This is probably a "pure" type Ia Supernova (M. Pruzhinskaya et al., Astron. Lett., Vol. 37, pp. 663-669, 2011), see also SN 2013D (ATel #4702). Spectral confirmation is required.
