Abstract

The long-term variations of EW Lac in the Hγ and Hβ line profiles are presented. The active phase observed in 1978–1982 is characterized by the strengthening of emission lines accompanied by variations of radial velocities andV/R asymmetries. A model of a rotating elliptic ring is proposed.
