Scientific paper

We report the new results of high sampling rate spectral monitoring of the radio galaxy 3C390.3 and the Seyfert galaxy Markarian 6 carried out at the 2.6-m telescope of BAO. We have observed narrow, small-amplitude, but significant profile changes in the broad Hα and Hβ emission lines on time scale of hours. Variability on time scales shorter than the light crossing time of the BLR can be used to test different kinematical models of broad emission line region of AGNs. Obtained results may indicate the response of rotating emitting gas (an accretion disk) with macroturbulence to a light pulse from a central source.
