MASTER OT J015539.85+485955.6 discovery - bright PSN in PGC212862

MASTER-IAC auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 01h 55m 39.85s +48d 59m 55.6s on 2015-11-07.99775 UT.
The OT unfiltered magnitude is 15.2m (limit 19.1m). The OT is seen in 5 images.
We have reference image without OT on 2015-08-02.08168 UT with unfiltered magnitude limit 18.4m.
This PSN is in 9.4"E,7.9"N from the center of PGC212862 galaxy with Btot=17.5m.

The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/015539.85485955.6.png

There is a possibility for the second scenario with the USNO B1 star in 0.5" with B2=19.98(20.5 GSC2.3.2) R2=19.25(19.6 GSC2.3.2). In this case there is a dwarf nova outburst with Ampl>4.6m
Spectral observations are required.
