Abstract:
The results of both BVRI CCD photometric monitoring and fast
photometry for 8 blazars and variable quasars are presented. There is
intraday variability for 6 blazars and very short timescales (minutes
to two hours) variability for 5 objects. Implications for relativistic
beaming are briefly discussed.
