摘要：
We present the results of monitoring of the integrated fluxes of variable extragalactic sources at 4.8 and 8.6 GHz at the Svetloe Radio Astronomy Observatory (Institute of Applied Astronomy, Russian Academy of Sciences) from 1999 up to the present. More than 1000 observations of 36 sources have been carried out over this monitoring interval. We describe some of the most interesting flares detected in a number of sources, including the well-known objects 0851+202, 3C 345, and BL Lac. Even observations of variability at two frequencies can be very useful for planning astrophysical and astrometric observations. We briefly discuss the possibility of enhancing the effectiveness of the monitoring by expanding the range of frequencies to 22 GHz and adding polarization observations.
