TITLE: GCN CIRCULAR NUMBER: 2073 SUBJECT: GRB 030329: Radio observations at GMRT DATE: 03/04/02 11:02:26 GMT FROM: D. Bhattacharya at Raman Research Inst. A. Pramesh Rao and C. H. Ishwara Chandra (National Centre for Radio Astrophysics, Pune, India), and D. Bhattacharya (Raman Research Institute, Bangalore, India) report on behalf of a larger collaboration: The GRB030329 was observed with the Giant Metrewave Radio Telescope (Khodad, India) for 8 hours on 31 March and for 5 hours on 01 April 2003. The observations were at 1288 MHz with a bandwidth of 8MHz and angular resolution of ~3.5". There was a detection of emission at the position of the GRB as shown below Date Time Flux Density rms noise 31 March 2003 14-22 UT 245 microJy 35 microJy 01 April 2003 18-22 UT 235 microJy 40 microJy It is at present unclear whether the detected flux is due to the burst or due to a background source that may or may not be associated with the burst.
