MASTER OT J122915.24+815214.3 discovery - possible SuperNova in UGC07624 spiral galaxy

MASTER-Kislovodsk auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 12h 29m 15.24s +81d 52m 14.3s on 2015-04-17.82831 UT.

This PSN unfiltered magnitude is 18.5m (the limit is 20.1m).

The OT is seen in 3 images. There is no minor planet at this place.

We have reference image without OT on 2012-10-20.69985 UT with 19.7 unfiltered magnitude limit (and about 200 images from 2009 to 2015 in MASTER-Kislovodsk, -Tunka and -Amur database).

This PSN is in 10.3"E and 3.7"N from the center of UGC07624 Scd galaxy Spectral observations are required.
