Abstract

The spectra of NGC 5548 galaxy nucleus obtained at the Crimean Aetrophysical observatory on 2.6-m Shain telescope from April till August 1985 showed strong variations of Hβ line profile. The profile being almost symmetrical in April became more and more asymmetrical in June-August, the flux in blue wing increased twofold in respect to the red one. Such variations of line profile were accompanied by continuum decrease.We suppose, that the observed variations might be explained by the appearance of the absorbing matter located on the line of sight between the nucleus and the gas responsible for the intensity increase in the blue wing of Hβ line. This gas might have been ejected close to the line of sight direction.
