MASTER OT J230024.63+013736.8 discovery - possible SuperNova in UGC12295

MASTER-Kislovodsk auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 23h 00m 24.63s +01d 37m 36.8s on 2015-08-06.90198 UT.

The OT unfiltered magnitude is 15.9m (the limit is 19.5m).

This PSN is seen in 3 images in 13.8"E and 1.4"N from the UGC12295 galaxy(z=0.016128). There is no minor planet at this place.

We have reference image without OT on 2010-11-06.74942 UT with 20.8 unfiltered magnitude limit in MASTER-Kislovodsk database.

Spectral observations are required.
