Optical Photometric and Radio Monitoring of Gamma-ray Loud Blazars
We present the results of multi-years optical and radio monitoring of radio-loud quasars 0716+714 and 1633+382, aimed at searching the flux variations and possible correlation at different wave bands. Our radio observations were performed with a 22-m radio telescope of the Crimean Astrophysical Observatory, 14-m radio telescope of the Metsahovi Radio Observatory and 26-m telescope of the Michigan Radio Astronomy Observatory at 4.8, 8.0, 14.5, 22.2 and 36.8 GHz. The optical observations were performed with a Zeiss-1000 reflector of the Special Astrophysical Observatory in the B, V, R filters. The harmonic analysis performed for the light curves of 0716+714 from 2002-2010 in radio and optical wave bands revealed the presence of an apparent periodical component in the flux variations. The period of the radio light curve is nearly 3.6 years, and coincides within the errors with the period of the optical light curve (nearly 3.4 years). The duration of the flares is approximately the same in radio and optical ranges, and it is about 100-150 days.
