MASTER OT J015249.50+154607.2 - possible supernova
MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 01h 52m 49.50s +15d 46m 07.2s on 2014-09-16.01830 UT. The OT unfiltered magnitude is 18.5m (limit 19.5m). The OT is seen in 4 images. There is no minor planet at this place. We have reference image without OT on 2010-11-01.85013 UT with unfiltered magnitude limit 19.8m.
The new object is located 5" west and 6.5" north of the nucleus of galaxy SDSS J015249.83+154600.7 (g=17.62 r=17.29 i=17.10) = GALEX J015249.9+154600 (FUV=19.25 NUV=19.00). There is a radio source AGC 748823 near this position in NED with coordinates 01h 52m 49.3s +15d 46m 01s and redshift z=0.04381 according to The Arecibo Legacy Fast ALFA Survey (M. Haynes et al., AJ 142, 170, 2011).
Spectral confirmation is required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/015249.50154607.2.png
