MASTER OT J080658.36+250049.7 discovery - possible SN in 14.1E,0.9S from the center of PGC1722882 galaxy

MASTER-Kislovodsk auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 08h 06m 58.36s +25d 00m 49.7s on 2015-05-25.77661 UT. The PSN unfiltered magnitude is 16.6m (the limit is 17.9m).

There are 2 images with this PSN. There is no minor planet at this place. There is PGC1722882 galaxy (SBb(r)) with v_hel=10887 and g_mag=15.6, and MASTER PSN is in 14.1E,0.9S from it.

We have reference image without OT on 2011-03-26.73848 UT with unfiltered magnitude limit 19.8m.

Spectral observations are required.
