TITLE: GCN CIRCULAR NUMBER: 18608 SUBJECT: GMRT radio detection of GRB 151027A DATE: 15/11/16 11:43:16 GMT FROM: Poonam Chandra at TIFR Poonam Chandra (NCRA-TIFR) and A. J. Nayana (NCRA-TIFR) reports: We carried out Giant Metrewave Radio Telescope (GMRT) observations of GRB 151027A (GCN Circ. 18478) at 1390 MHz band on 2015 Nov 15.19 UT. We detect the radio afterglow of the GRB in the Swift error circle (GCN Circ. 18482). The 1390 MHz band flux density of the afterglow is 312+/-64 uJy. Map rms is 37 uJy. Further observations are planned. We thank GMRT staff for making these observations possible. -- _________________________________________ Poonam Chandra National Centre for Radio Astrophysics Tata Institute of Fundamental Research Pune University Campus, Ganeshkhind Pune 411007, Maharashtra, INDIA Phone: +91 20 2571 9290 Fax: +91 20 2569 7257 Email: poonam@ncra.tifr.res.in Web: www.ncra.tifr.res.in:8081/~poonam/ _________________________________________
