MASTER OT J071956.13-645810.1 - CV?
MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 07h 19m 56.13s -64d 58m 10.1s on 2015-01-15.95972 UT.
The OT unfiltered magnitude is 17.5m (limit 20.0m).
The OT is seen in 4 images. There is no minor planet at this place.
We have reference image without OT on 2014-12-21.95389 UT with unfiltered magnitude limit 20.4m.
There is GALEX-DR5 (GR5) source at this place.
So UV radiation emitted by accreting White Dwarf demonstrated that MASTER OT J071956.13-645810.1 is the New CV.
Spectral observations are required.
