Ralph Martin (Perth Observatory) report:

We observed the SWIFT-UVOT position of the GRB081007 afterglow (GCN 8330) at 4.800 and 4.928 GHz with the Australia Telescope Compact Array (ATCA) between 01:00:00 UT and 22:00:00 UT on February 21/22, 2009.

We did not detect a radio source at the position of the GRB081007 (GCN 8330). The data at 4.800 and 4.928 GHz were merged and the radio flux density at the GRB optical afterglow position found out to be -0.215 +/- 0.006 mJy/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.
