GCN Circular 4715
A.J. van der Horst (University of Amsterdam) reports on behalf of a larger collaboration: "We observed the position of the GRB 060206 afterglow at 4.9 GHz with the Westerbork Synthesis Radio Telescope at February 7 21.89 UT to February 8 9.86 UT, i.e. 1.71 - 2.21 days after the burst (GCN 4682). We do not detect a radio source within the SWIFT/XRT error circle (GCN 4689), in particular at the position of the optical counterpart (GCN 4683, GCN 4684). The formal flux measurement for a point source at the position of the optical counterpart is 39 +/- 22 microJy. We note there is a bright radio source at RA 13h31m44.2s, Dec +35d03'04.6" (+/- 0.5 arcsec, J2000), i.e. 12 arcsec offset from the optical/X-ray counterpart position, with a flux of 738 +/- 28 microJy."
