MASTER OT J163746.50+114950.0 - QSO flare
MASTER-IAC auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 16h 37m 46.50s +11d 49m 50.0s
on 2017-05-06 2017-05-06 01:43:58UT .
The OT unfiltered magnitude is 16.3 (mlim=19.6).It was 17.0m at min state on 2016-04-27 02:35:08.773UT
There is QSO in 0.43" (Hewitt+ 1993, Schneider+ 2010, et al)
The discovery and reference image are available at
MASTER OT J181624.72+073252.7 discovery - OT with ampl>3.4m
MASTER-IAC auto-detection system discovered OT source at (RA, Dec) = 18h 16m 24.72s +07d 32m 52.7s on 2017-05-07.19602 UT.
The OT unfiltered magnitude is 18.6m (limit 19.2m).
The OT is seen in 4 images. There is no minor planet at this place.
We have reference image without OT on 2016-07-09.98615 UT with unfiltered magnitude limit 19.3m.
There is GSC2.3.2 star with known only Nmag, it means 22m POSS limit in history and more then 3.4m of current amplitude.
Spectral observations are required.
