TITLE: GCN CIRCULAR NUMBER: 738 SUBJECT: GRB000630, Radio Observations DATE: 00/07/01 03:13:42 GMT FROM: Edo Berger at Caltech E. Berger (Caltech) and D. A. Frail (NRAO) report on behalf of a larger collaboration: "On July 1.04 UT we used the VLA at 4.86 GHz to observe the IPN error region of GRB000630 (GCN 736). Inside the error region we find one bright radio source, which is not present in either the NRAO VLA Sky Survey (NVSS) or the Faint Images of the Radio Sky at Twenty-cm (FIRST) survey (note that both these surveys are at 1.43 GHz). The position of the source is RA=14 46 58.8, DEC=41 16 59.0 with a conservative error of 1". A limit of 0.1 mJy can be placed on the absence of a radio source at the position of the optical source reported by Bartolini et al. (GCN 737). Further observations are planned."
