TITLE: GCN CIRCULAR NUMBER: 5726 SUBJECT: GRB 061007: Second Epoch ATCA Radio Observations DATE: 06/10/12 22:15:17 GMT FROM: Alexander van der Horst at U of Amsterdam A.J. van der Horst (University of Amsterdam) and E. Rol (University of Leicester) report on behalf of a larger collaboration: "We reobserved the position of the GRB 061007 afterglow at 4.8, 8.6 and 19 GHz with the Australia Telescope Compact Array at October 12 10.87 UT to 16.78 UT, i.e. 5.03 - 5.28 days after the burst (GCN 5707). We do not detect a radio source at the position of the optical afterglow (GCN 5706). The formal flux measurement for a point source at the location of the optical afterglow is -1 +/- 43 microJy at 4.8 GHz, -37 +/- 46 microJy at 8.6 GHz, and -1 +/- 47 microJy at 19 GHz. We would like to thank the staff of the Australia Telescope National Facility, in particular Philip Edwards, for obtaining these Target of Opportunity observations."
