MASTER OT J054746.81+762018.9 discovery - new OT, poss.dwarf nova outburst, Ampl>5.3m, no VIZIER data
MASTER-IAC auto-detection system discovered OT source at (RA, Dec) = 05h 47m 46.81s +76d 20m 18.9s on 2016-10-12.03463 UT with unfiltered magnitude m_OT=16.7m (mlim=18.5m).
The OT is seen in 3 images. There is no minor planet at this place. There is no any sources in VIZIER database, i.e.22m POSS limit and more then 5.3mag of amplitude of current outburst.
We have reference image without OT on 2015-11-12.14416 UT with unfiltered mlim=20.2m.
Spectral observations are required.
