MASTER OT J140356.92-095636.6 discovery- new OT with outburst ampl>6.5m
AT2020mqn
During inspection of High Energy Muon Neutrinos alert [1,2] BAKSAN200614.34 (Lipunov et al. GCN #27946)
MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 14h 03m 56.92s -09d 56m 36.6s on 2020-06-14.96831 UT.
The OT magnitude in unfiltered is 17.5m(mlim=19.3).
The OT is seen in 4 images. There is no minor planet at this place.
We have reference images : 2018-01-21.29825 UT with unfiltered 19.8m, 2019-02-28 02:56:08UT with mlim=18.0
VIZIER has no information at these coordinates, SIMBAD has no sources, it gives 22m POSS limit in history and more then 4.5mag amplitude value of current outburst.There is no sources at PanSTARRS images, that gives 24m in R(close to MASTER unfiltered) and more then 6.5 m of current outburst amplitude
Spectral observations are required.
