Scientific paper

New photoelectric photometry of 11 Seyfert galaxies is presented, which confirms the anomalous color of the regions around the nuclei. The inner zones are bluer than the corresponding regions in normal galaxies of the same morphological type due to enhanced star-formation activity. A correlation between the ring color in the galaxies and the luminosity of their active nucleus is observed, and the nuclear regions of Seyfert galaxies resemble the highly structured hot spot nuclei that occur in some normal galaxies.
