MASTER OT J190939.00-350257.9 discovery - new OT, ampl>5.6m
MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net",
Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 19h 09m 39.00s -35d 02m 57.9s on 2019-05-15.37023 UT.
The OT unfiltered magnitude is 16.7m (mlim=18.3m).
The OT is seen in 3 images. It was also detected at MASTER-SAAO on 2019-05-13 22:29:02.293UT(2 images) with m_OT=16.4
We have reference image without OT on 2018-09-03.09686 UT with unfiltered magnitude limit 19.5m.
There is no any sources in AAVSO and VIZIER database(it means 22m POSS limit and more then 5.6m of current outburst amplitude)
Spectral observations are required.
The discovery and reference images are available at:
