MASTER OT J115158.31-472158.9 discovery - CV, ampl>5m
MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 11h 51m 58.31s -47d 21m 58.9s on 2017-11-12.09500 UT.
The OT unfiltered magnitude is 16.8m (mlim=18.1).
The OT is seen in 3 images. There is no minor planet at this place. There is no known sources in VIZIER inside 4".The nearest source is GSC2.3.2(USNO-B1) star in 4.7" with only blue (1977.221) jmag=20.8, it means more then 5m amplitude of current outburst.
We have reference image on 2016-08-04.73343 UT with unfiltered mlim= 20.3m.
Spectral observations are required.
