MASTER Global Robotic Net (Lipunov et al., Advances in Astronomy, 2010, 30L)
reports on an enhanced optical activity of the flaring flat-spectrum radio quasar PKS B1149-084 (Angioni et al. ATel #14450).
Following the announcement of its flaring state from Fermi-LAT Collaboration
MASTER-OAFA started unfiltered observations of this source at 2021-03-10 08:44 UT with an exposure time of 60s and 180s.
We obtained 6 frames that were used for photometry.
The source was detected with m=18.5+-0.2 mag.
We have reference image on 2020-02-25 with m_PKS=19.1+-0.3 mag .
We encourage further multi-wavelength observations of this source.
