Abstract
We present V (Johnson) and RI (Cousins) magnitudes of eld comparison stars for 12 bright Seyfert galaxies. These stars are closer than 6 0 (typically 3 0 4 0 ) to the galaxy and have V magnitudes between 10 m and 6 m . The sequences could be used for CCD monitor- ing and dierential photometry of these active galaxies, aimed to better understanding the physics of their vari- ability. Photometric errors of measured stars are in the range 0: m 03 0: 06. Finding charts (15 0 15 0 ) are also included.
