MASTER OT J034115.13+152303.9 - PSN Ia

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 03h 41m 15.13s +15d 23m 03.9s on 2013-01-03.82235 UT. The OT unfiltered magnitude is 17.5m (limit 19.8m). The OT is seen in 4 images. There is no minor planet at this place. We have reference image without OT on 2010-12-03.84887 UT with unfiltered magnitude limit 22.5m.

There is elliptical galaxy group around OT. The robot gives the most probably candidate is PGC1483058 with OT offset: 23.3E 19.9N arcsec. This is possible so called "Pure" SN Ia ( Pruzhinskaya, M. V. et al., Astronomy Letters, Volume 37, Issue 10, pp.663-669, 2011).

Spectral observations are required.
