MASTER OT J185835.32-354042.2 discovery - new OT, preliminary dwarf nova outburst, ampl>5.3m
MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 18h 58m 35.32s -35d 40m 42.2s on 2018-04-12.08618 UT.
The OT unfiltered magnitude is 16.7m (mlim=19.0).
The OT is seen in 2 image. There is no minor planet at this place.
We have reference image on 2015-08-15.96315 UT with unfiltered mlim= 19.0m.
There is no any known sources in VIZIER database, it means 22mag POSS limit and more then 5.3mag of current amplitude.
Spectral observations are required.
