MASTER OT J153519.70-063028.9 detection - dwarf nova outburst, ampl>3m
MASTER-OAFA auto-detection system discovered OT source at (RA, Dec) = 15h 35m 19.70s -06d 30m 28.9s on 2018-06-06.96657 UT.
The OT unfiltered magnitude is 17.2m (limit 18.3m).
The OT is seen in 3 images. There is no minor planet at this place.
We have reference image with m_OT~mlim~20.2 on 2018-05-14.96376 UT.
There is USNO-B1 star with r2mag=20.95,B2mag=20.44 (MASTER_W=0.2B+0.8R), so the current outburst amplitude is more then 3mag
Spectral observations are required.
The discovery and reference images are
