GCN Circular 6549
A.J. van der Horst, R.A.M.J. Wijers, K. Wiersema (University of Amsterdam), and E. Rol (University of Leicester) report on behalf of a larger collaboration: "We observed the position of the GRB 070612A afterglow (GCN 6509) at 4.9 GHz with the Westerbork Synthesis Radio Telescope at June 15 8.10 UT to 20.09 UT, i.e. 3.23 - 3.73 days after the burst. We tentatively detect a radio source at 3 sigma significance, located at the position of the optical counterpart (GCN 6515, GCN 6525), with a flux of 78 +/- 25 microJy. Further observations at radio wavelengths of this afterglow are planned and encouraged, especially given the suggested association with a nearby low-redshift host galaxy (GCN 6525). We would like to thank the WSRT staff for scheduling and obtaining these observations."
