TITLE: GCN CIRCULAR NUMBER: 16591 SUBJECT: Radio upper limits on the GRB 140703A with the GMRT DATE: 14/07/15 08:41:55 GMT FROM: Poonam Chandra at TIFR A. J. Nayana (NCRA-TIFR) and Poonam Chandra (NCRA-TIFR) reports: We carried out Giant Metrewave Radio Telescope (GMRT) observations of GRB 140703A (GCN 16503) in the 1390 MHz band on 2013 July 10.12 UT and 12.91 UT, respectively. We do not detect the radio afterglow of the GRB in this frequency. The 3-sigma upper limit at the two epochs are 174 and 177 uJy, respectively. The map resolutions of the two images are 2.5"x2.0" and 3.1"x2.1", respectively. We thank GMRT staff for making these observations possible.
