In 2018, we implemented the mode of fast radiometry with a discretization
interval from 60 to 490 μs at the 4.7 GHz sensitive radiometer for the first time.
In 2018 February on the 6-m BTA telescope of the SAO RAS we carried out a 9-hour
photometric and polarimetric monitoring of S5 0716+714 using the SCORPIO spectrograph.
Using various techniques of optical observations at the 6-m Russian telescope
(direct images, long-slit and 3D spectroscopy), we have studied distribution
and motions of the ionized gas in the galaxy Mrk 6 having an active (Seyfert)
