of scientific and scientific-engineering papers of the Observatory staff members A unique set of linear polarization measurements in the spectrum of the Seyfert galaxy Mkn 6 was obtained with the 6-meter telescope. It was shown for the first time that the analysis of the polarization angle dependence on the velocity across the hydrogen line profiles due to the gas emission in the broad-line formation region near the massive AGN allows to determine directly from observations the type of motion in the broad-line formation region, which in the case of Mkn 6 turned out to be Keplerian at distances less than 0.02 pc from the nucleus. The lower mass limit determined for the supermassive black hole in the center of the Mkn 6 galaxy is equal to 150 million solar masses.
