Abstract

We present the results of intraday variability observations in compact extragalactic radio sources with the 25 m radio telescope of Urumqi Astronomical Observatory at 5 GHz. In total we have observed 116 flat-spectrum sources, of these, 17 show IDV. We present here a summary table of the results, as well as the light curves and structure functions of a few sources. Either interstellar scintillation or an intrinsic origin could be the cause of the variability in these IDV sources. Further observations over a longer time scale are needed to explain the IDV.
