Ralph Martin (Perth Observatory) report:

We observed the BAT refined position of the GRB 080218b (GCN 7314) at 4.8 and 8.456 GHz with the Australia Telescope Compact Array on May 31, 2008 between 04:24:45 UT and 10:15:15 UT.

We did not detect a radio source at the BAT position of the GRB 080218b (GCN 7314). The radio flux density at the GRB position is -0.286 +/- 0.252 mJy at 4.8 GHz, and -0.350 +/- 0.271 mJy at 8.6 GHz (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.
