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 SWIFT-BAT refined position of the GRB 080218b (GCN 7325)
at 4.8 and 8.456 GHz with the Australia Telescope Compact Array (ATCA)
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 7325). 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 8.456 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.
