J/AZh/81/925 R light curves of 5 blazars (Bychkova+, 2004) ================================================================================ The Rapid Variability of Blazars at Optical Wavelengths. Bychkova V. S., Kardashev N.S., Vlasyuk V.V., Spiridonova O.I. =2004AZh....81..925B =2004ARep...48..840B ================================================================================ ADC_Keywords: Active gal. nuclei ; Photometry, CCD 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.
