Abstract:
We monitored five active galactic nuclei in the R optical band with a
CCD mounted on the 1-m Zeiss-1000 telescope of the Special
Astrophysical Observatory from April 2001 to August 2003. Three
sources displayed intraday variability on several nights. Stronger
variability was detected on time scales from two days to a week. The
two-year light curves are presented for four of the observed objects.
