Аннотация:AGN optical spectra (4000-5000Å) are being observed with the TV scanner of the 6 m telescope at Special Astrophysical Observatory (N. Arkhyz-North Caucasus) since 1986 till now. The usual dispersion is 1Å/channel, the signal-to-noise ratio in individual spectra is S/N = 10-25. NGC 4151, NGC 3516, NGC 5548, and NGC 7469 are the main objects of the programme. Strong variations of H, H, H, and HeII 4686Å line intensities and profile shapes have been observed on a time scale from 10-30 days to several years. The data are being used in international AGN watch programmes for diagnosis, estimation of the size and structure of the BLR.
