MASTER OT J013254.75-013727.2 - PSN in PGC 1114159

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 01h 32m 54.75s -01d 37m 27.2s on 2014-11-10.91825 UT. The OT unfiltered magnitude is 18.3m (limit 19.5m). The OT is seen in 5 images. There is no minor planet at this place. We have reference image without OT on 2011-09-27.99019 UT with unfiltered magnitude limit 20.1m.

The OT is located 19" west and 22" north of the center of galaxy PGC 1114159 = 6dFGS gJ013256.0-013750 = SDSS J013256.01-013749.2 (z=0.0796) with distance modulus m-M=37.8. The new object is possibly a "pure" type Ia supernova (M. Pruzhinskaya et al., Astron. Lett., Vol. 37, pp. 663-669, 2011), see also SN 2013D (ATel #4702, P. Balanutsa et al., 2013). Spectral confirmation is required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/013254.75-013727.2.png
