TITLE: GCN CIRCULAR NUMBER: 18620 SUBJECT: 610 MHz detection of GRB 151027A with the GMRT DATE: 15/11/19 10:52:47 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 610 MHz band on 2015 Nov 19.19 UT. We detect the radio afterglow of the GRB in the Swift error circle (GCN Circ. 18482). The 610 MHz band flux density of the afterglow is 522+/-94 uJy. Map rms is 56 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/ _________________________________________
