- Аннотация: The results are given of photoelectric photometry with resolution 50-100 A and simultaneous UBVR photometry of 25 galaxies, including 22 objects of Seyfert type. Variability has been found in the energy distribution in the continuum of the nuclei of the galaxies NGC 4151 and Mkn 279. In the region lambda less than or approximately equal to 4000 A, the Sy 1 objects have a flux excess in the continuum compared with a power-law spectrum. The intensities of the hydrogen lines in the spectrum of the nucleus of NGC 7469 increase linearly with increasing flux in the continuum, whereas the intensities of the forbidden lines remain unchanged.
