On behalf of a larger collaboration, the field of SN 2011ja was observed with the Giant Metrewave Radio Telescope (GMRT) for 6 hours centred on 2012 January 11.0 UT at an effective frequency of 1264 MHz with a bandwidth of 32 MHz. The image is dynamic range limited, due to the bright host galaxy which also has significant extended emission. The flux density at the position of the supernova is 2+/-1 mJy. We put a 3 sigma upper limit of 3 mJy on the source flux. We thank the Director GMRT for granting this DDT observation and the staff of the GMRT that made this observation possible. GMRT is run by the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research.
