TITLE: GCN CIRCULAR NUMBER: 7201 SUBJECT: XRF 080109 / SN 2008D: GMRT radio observation at 1280 MHz DATE: 08/01/22 08:26:48 GMT FROM: Sabyasachi Pal at GMRT Sabyasachi Pal (NCRA/TIFR), A. Kamble (University of Amsterdam) and Dipankar Bhattacharya report on behalf of a larger collaboration The position of XRF 080109 / SN 2008D was observed by Giant Meterwave Radio Telescope (GMRT) as ToO at 1280 MHz. The observation took place from UT 20.68 to 21.00 January, 2008. It was started after 11.11 days of the beginning of the burst (GCN 7172). The preliminary analysis suggest that the upper limit of the flux density at the position of XRF 080109 (GCN 7190, GCN 7178) is 160 microJy with 235 micro Jy three sigma noise level. One sigma rms noise of the image is 45 microJy. We thank the staffs of the GMRT who have made this ToO observation possible and have given the data to us. GMRT is run by the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research.
