TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5390 SUBJECT: GRB 060801: WSRT Radio Observations DATE: 06/08/03 01:29:48 GMT FROM: Alexander van der Horst at U of Amsterdam A.J. van der Horst (University of Amsterdam) reports on behalf of a larger collaboration: "We observed the position of the GRB 060801 afterglow at 4.9 GHz with the Westerbork Synthesis Radio Telescope on Aug 2 from 11.03 to 23.01 UT, i.e. 0.95 - 1.45 days after the burst (GCN 5378). We do not detect a radio source within the XRT error circle (GCN 5382) or the refined XRT/SDSS error circle (GCN 5389), in particular at the position of the optical sources mentioned in GCN 5384 and GCN 5386. The rms noise in het map within the SWIFT/XRT error circle is 24 microJy per beam. The formal flux measurement for a point source at the center of the XRT error circle is 32 +/- 24 microJy. We detect two sources close to the XRT error circle which are also present in the FIRST survey at 1.4 GHz. These sources have fluxes of 854 +/- 37 microJy (RA(J2000)=14h12m00.39s, Dec(J2000)=16d59m05.3s) and 1031 +/- 37 microJy (RA(J2000)=14h12m01.18s, Dec(J2000)=16d59m06.7s) at 4.9 Ghz."
