Abstract

We report JVLA 8-10 GHz ($\lambda$=3.0-3.7 cm) monitoring observations toward the YSO cluster R Coronae Australis (R\,CrA), taken in 2012, from March 15 to September 12. These observations were planned to measure the radio flux variabilities in timescales from 0.5 hours to several days, to tens of days, and up to $\sim$200 days. We found that among the YSOs detectable in individual epochs, in general, the most reddened objects in the \textit{Spitzer} observations show the highest mean 3.5 cm Stokes \textit{I} emission, and the lowest fractional variabilities on $ $
