Since 1986, we have carried out spectral monitoring of several Seyfert galaxies with the 6-m telescope of SAO RAS to study the structure and kinematics of the broad-line regions (BLR). Here we present the observational results for NGC 4151 and 3C 390.3.
In 1986–96, about 150 spectra of the NGC 4151 nucleus were obtained with SP124+TV scanner and 24 spectra with a long-slit (UAGS+CCD) or a multipupil field spectrograph (MPFS + CCD). About 20 spectra of 3C 390.3 were obtained in 1995–96 with the UAGS + CCD and with MPFS + CCD. More detailed information about observations, data processing and results will appear in Shapovalova et al. (1996).
