The GMRT observed SN2007bg (Quimby et al. 2007, CBET #927; Prieto et al. GCN #9444; Soderberg A. M., ATel #2066) on 26th June and 1st July 2009 at 610 and 1280 MHz, respectively. The SN was not detected at 610 MHz to a three sigma upper limit of 225 microJy. The measured brightness of SN2007bg are as follows :
date Freq. (MHz) days since discovery Flux (mJy)
26 Jun 2009 610 ~ 802 < 0.225 (3 sigma)
01 July 2009 1280 ~ 806 1.2 +/- 0.14
The 'days since discovery' are estimated following Prieto et al. (GCN #9444). These results are indicative that the source is optically thick at 610 MHz.
