MASTER OT J222438.99+105729.5 discovery - QSO flare ?

MASTER-IAC auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 349171 ) discovered OT source at (RA, Dec) = 22h 24m 38.99s +10d 57m 29.5s on 2016-06-14.08069 UT.
The OT unfiltered magnitude is 16.7m (the limit is 17.9m). The OT is seen in 6 images. We have reference images without OT on 2015-10-06.95291 UT with unfiltered magnitude limit 20.2m at MASTER-IAC database and on 2014-09-22 18:14:29UT at MASTER-Kislovodsk.
We have previous flare on 2014-05-10 23:55:22UT with m_OT=17.6 in MASTER-Kislovodsk database.
This OT is a source from SDSS DR10 catalogue of candidate quasars (Brescia+, 2015)

Spectral observations are required.
