BVRI photometry of blazars
Listed in IVOA Registry (Virtual Observatory)
The results of both BVRI CCD photometric monitoring and fast photometry for 8 blazars and variable quasars are presented.
Description
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.
