MASTER OT J051233.07-462122.7 discovery - PSN in 2MASX J05123156-4621194 galaxy

MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 349171 ) discovered OT source at (RA, Dec) = 05h 12m 33.07s -46d 21m 22.7s on 2016-04-27.77351 UT.
The OT unfiltered magnitude is 18.1m (limit 20.4m).
The OT is seen in 3 images. There is no minor planet at this place.
We have reference image without OT on 2014-12-24.95295 UT with unfiltered magnitude limit 20.3m.

This PSN is in 15.88" from the 2MASX J05123156-4621194 galaxy (300Mpc, Bj=16.8m, Rj=15.4m, 6dF Sp)

Spectral observations are required.
