MASTER OT J023414.54+454307.3 discovery - new OT, possibl.dwarf nova outburst, ampl>5.7m
MASTER-Amur auto-detection system discovered OT source at (RA, Dec) = 02h 34m 14.54s +45d 43m 07.3s on 2017-09-08.74044 UT.
The OT unfiltered magnitude is 16.3m (limit is 17.8m).
The OT is seen in 3 images. There is no minor planet at this place.
We have reference image without OT on 2016-10-08.74078 UT with unfiltered magnitude limit 18.0m, on 2014-08-22 22:32:28UT with mlim=19.8 in MASTEr-Kislovodsk database.
There is no any sources in VIZIER database, it means 22m POSS limit in history and more then 5.7mag of current outburst's amplitude.
Spectral observations are required.
