MASTER OT J004528.12+414117.6 discovery - possible Nova in M31

MASTER-Kislovodsk auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 349171 ) discovered OT source at (RA, Dec) = 00h 45m 28.12s +41d 41m 17.6s on 2016-04-10.03461 UT.

The OT unfiltered magnitude is 19.0m (the limit is 19.5m).

The OT is seen in 3 image. There is no minor planet at this place. We have reference image without OT on 2016-02-08.68476 UT with unfiltered magnitude limit 21.1m.

We reobserved it with unfiltered m_OT=18.6 on 2016-04-13 05:11:28.249UT in MASTER-IAC

Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/004528.12414117.6.png
