TITLE: GCN CIRCULAR NUMBER: 7684 SUBJECT: GRB 080503: VLA radio upper limit DATE: 08/05/06 17:37:33 GMT FROM: Poonam Chandra at U Virginia/NRAO Dale A. Frail (NRAO) and Poonam Chandra (NRAO/UVA) report on behalf of the Caltech-NRAO-Carnegie GRB Collaboration: "We used the Very Large Array to observe the field of view toward GRB 080503 (GCN 7665) at a frequency of 8.46 GHz at 2008 May 6.57 UT. We do not detect the GRB afterglow in 2.5 hours of VLA observations. The 3-sigma upper limit on the afterglow flux is 54 uJy (rms 18 uJy).
