TITLE: GCN CIRCULAR NUMBER: 20344 SUBJECT: GMRT radio detection of GRB 161219B DATE: 16/12/27 16:44:35 GMT FROM: Nayana A J at NCRA-TIFR A. J. Nayana (NCRA-TIFR) and Poonam Chandra (NCRA-TIFR) reports: We carried out Giant Metrewave Radio Telescope (GMRT) observations of GRB 161219B (D'Ai et al. GCN Circ. 20296) in the 1390 MHz band on 2016 Dec 26.68 UT. We detect the radio afterglow of the GRB in the Swift error circle (Beardmore et al. GCN Circ. 20297). The 1390 MHz band flux density of the afterglow is 397+/-55 uJy. Map rms is 40 uJy/beam. Further observations are planned. We thank GMRT staff for making these observations possible.
