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)
Radiation of the 4th harmonica of the gyro-frequency in the Solar corona
above the spot was detected due to detailed spectroscopic observations
at RATAN-600 with high-accuracy polarization measurements.
From observations carried out with the telescopes BTA/SCORPIO and VLT/UVES and
from data of new catalogs SDSS-III and others, the characteristic signatures of
the clustering of field galaxies with a redshift of z≈0.56
around the gamma-ray burst GRB 021004 position were detected.
