MASTER OT J111326.87-763146.0 discovery - XMM source's (AGN?) optical outburst discovery, ampl>5.2m
MASTER-OAFA (located in Argentina) auto-detection system
( Lipunov et al., "MASTER Global Robotic Net",
Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 11h 13m 26.87s -76d 31m 46.0s on 2016-11-30.33949 UT.
The OT unfiltered magnitude is 16.8m (limit 19.3m).
The OT is seen in 3 images. We have reference image without OT on 2016-08-07.04407 UT with unfiltered magnitude mlim=19.7m.
There is GALEX and XMM source, also known as AGN (Lin et al., 2012).
22mag POSS limit gives more then 5.2m amplitude of current optical outburst
Spectral observations are required.
