Abstract

Optical spectra of the NGC 4151 with the TV scanner of the 6-meter telescope in 1986–1991 are presented. Spectra averaged over periods of ≈ 2.5 months show changes of asymmetry of the He II λ4686 Å broad emission line with a characteristic time scale ≈ 2 years (the full cycle of the changes is approximately 4 years). Possible explanations involving a precession-type of movement of cones of ionizing radiation are discussed.
