MASTER OT J215050.94-702028.9 discovery - possible SN in bright spiral edge-on NGC7123

MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 349171 ) discovered OT source at (RA, Dec) = 21h 50m 50.94s -70d 20m 28.9s on 2015-11-27.87081 UT.

The OT unfiltered magnitude is 14.5m (the limit is 18.4m).

The OT is seen in 4 images. There is no minor planet at this place. We have reference image without OT on 2015-07-13.18993 UT with unfiltered magnitude limit 19.5m.

This PSN is in 22.1E and 25.9S from the NGC7123

Spectral observations are required.
