【 摘 要 】

As one of the targets of many flux monitoring campaigns, FSRQ 0507 + 179 shows various flux variation properties at almost all observing wavelengths, from radio to 𝛾-ray. With Urumqi 25-m telescope, our study on this object is focussed mainly on its radio flux variability, especially the Intra-Day Variability (IDV). We carried out a total of six epochs of IDV observations on 0507+179 at 4.8 GHz since March 2010, and found clearly IDV behaviours in all observing sessions and considered it is likely a type-I IDV source by analysing the characteristics and the timescales of the light curves. Additionally, we found 0507+179 exhibited some different IDV behaviours after an optical flare.
