"We observed a region covering the Swift burst GRB 050315 (GCN#3094)
using the Australia Telescope Compact Array for 1 hour centered on
March 16.02 UT. At frequencies of 4.8 and 8.6 GHz no emission was
detected within the 6 arcsec diameter error circle of the XRT position
(GCN#3097). The 3-sigma detection limits are 0.6 and 0.8 mJy at 4.8 and
8.6 GHz respectively. No detections above these limits are present
in a larger area (1 arcmin diameter) around the XRT position."
We thank the ATNF Director for making this rapid response possible.
