TITLE: GCN CIRCULAR NUMBER: 6853 SUBJECT: Radio detection of GRB 071003 with the VLA DATE: 07/10/05 20:13:04 GMT FROM: Poonam Chandra at U Virginia/NRAO P. Chandra (UVA/NRAO) and D. A. Frail (NRAO) report on behalf of the Caltech-NRAO-Carnegie GRB Collaboration: "We observed the field centered on the BAT position of the Swift burst GRB 070923 (GCN#6837) using the VLA at a frequency of 8.46 GHz and starting at 1.85 UT on Oct 5, 2007. We detect the radio afterglow at KAIT optical position (GCN#6838) with flux density of 393 +/- 55 uJy. Further observations are planned.
