TITLE: GCN CIRCULAR NUMBER: 8642 SUBJECT: Radio observation of GRB 081118 with ATCA DATE: 08/12/09 02:03:37 GMT FROM: Aquib Moin at CIRA/ATNF Aquib Moin (Curtin Institute of Radio Astronomy / Australia Telescope National Facility), Steven Tingay (Curtin Institute of Radio Astronomy), Chris Phillips (Australia Telescope National Facility), Gregory Taylor (University of New Mexico), Mark Wieringa (Australia Telescope National Facility) and Ralph Martin (Perth Observatory) report: We observed the VLT position of the GRB 081118 optical afterglow (GCN 8528) at 4.800 and 4.928 GHz with the Australia Telescope Compact Array (ATCA) between 01:15:05 UT, November 24, 2008 and 20:35:30 UT, November 25, 2008. We did not detect a radio source at the optical afterglow position of the GRB 081118 (GCN 8528). The data at 4.800 and 4.928 GHz were merged and the radio flux density at the afterglow position found out to be -89 +/- 5.6 uJy/beam (1-sigma). The Australia Telescope Compact Array (/ Parkes telescope / Mopra telescope / Long Baseline Array) is part of the Australia Telescope which is funded by the Commonwealth of Australia for operation as a National Facility managed by CSIRO.
