reports on an enhanced optical activity of the flaring quasar TXS 1700+685(Cheung et al. ATel #14463),following the announcement of its gamma-ray flaring state from Fermi-LAT Collaboration.
MASTER-Kislovodsk started set of unfiltered observations of this source at 2021-03-16 18:06:45UT with an exposure time of 180s and m_OT=16.2 at first exposition .
We obtained 8 frames that demonstrate fast variability.
We have reference image at 2020-07-24 22:37:29UT with unfiltered m_OT=18.7.
Observation will be continued.
We encourage further multi-wavelength observations of this source.
