MASTER OT J084232.51-843025.5 discovery - possible SN in ESO006-004

MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 349171 ) discovered OT source at (RA, Dec) = 08h 42m 32.51s -84d 30m 25.5s on 2015-11-22.03715 UT.

The OT unfiltered magnitude is 17.1m (the limit is 19.2m).

There are 3 images with OT. There is no minor planet at this place. We have reference image without OT on 2015-03-09.99288 UT with unfiltered magnitude limit 19.2m.

This PSN is in 9.6"W and 3.3"S from the ESO006-004 galaxy (Ned:165Mpc, (m-M)=36.09mag, Leda:Bt=16.1)

Spectral observations are required.
