Аннотация: The results of panoramic spectrophotometry of the nucleus region of 3C390.3, obtained with the 6 m telescope in spring 1995, are presented. It is shown that radiation in [OIII] emission lines corresponds to the region with r \lt 2”. Blue and red ”bumps” of the profile of the H emission line have approximately similar velocities relative to its narrow component (\plusmn3500 km s-1). Ratios of their fluxes confirm sinusoidal dependence with a period of 10 years and correspond to maximum values of 1975, 1985. Gauss-analysis of H and [OIII] line profiles shows the possible presence of a component with intermediate velocity dispersion (\gt 1000 km s-1) at the same velocities as in the narrow component.
