TITLE: GCN CIRCULAR NUMBER: 19848 SUBJECT: Possible radio detection of GRB160623A with the GMRT DATE: 16/08/23 09:54:20 GMT FROM: Nayana A J at NCRA-TIFR A.J Nayana (NCRA-TIFR), Poonam Chandra (NCRA-TIFR), A. R. Rao (TIFR), Dipankar Bhattacharya (IUCAA) and Varun Bhalerao (IUCAA) report: We carried out Giant Metrewave Radio Telescope (GMRT) observations of GRB 160623A (Vianello et al. GCN Circ. 19553) at 1460 MHz band on 2016 Aug 04.91 UT. We detect a 4.5-sigma source at the GRB position (Vianello et al. GCN Circ. 19553) with a flux density of 207+/-78 uJy. This is most likely the radio afterglow of GRB 160623A. Map rms is 50 uJy. We thank GMRT staff for making these observations possible.
