TITLE: GCN CIRCULAR NUMBER: 10697 SUBJECT: GRB 100414A : WSRT Radio Detection DATE: 10/04/28 14:58:30 GMT FROM: Atish Kamble at U. of Amsterdam A.P. Kamble (U of Amsterdam), A.J. van der Horst (NASA/MSFC/ORAU), R.A.M.J. Wijers, E. Rol (U of Amsterdam), C. Kouveliotou (NASA/MSFC) and K. Wiersema (U of Leicester) report on behalf of a larger collaboration : "We observed the field of Fermi GBM/LAT burst GRB 100414A (GCN 10594, 10595, 10649) using the Westerbork Synthesis Radio Telescope at 4.8 GHz from April 27, 16.0 UT to April 28, 04.0 UT, i.e. 13.57 to 14.1 days after the burst. We detect the radio afterglow with flux density of 420 +/- 38 microJy at the position of the optical afterglow detected by GROND (GCN 10607). We would like to thank the WSRT staff for rapidly scheduling and obtaining these observations."
