TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3676 SUBJECT: GRB050724: Radio Observation DATE: 05/07/25 21:19:00 GMT FROM: Patrick B. Cameron at Caltech P. B. Cameron (Caltech) and D. A. Frail (NRAO) report on behalf of the Caltech-NRAO-Carnegie collaboration: "We observed the field of GRB050724 (GCN 3665) with the Very Large Array at 8.5 GHz on July 25.09. We identify one radio source that is ~9" west from the center of the XRT error circle (GCN#3669). Its position is (J2000): RA= 16:24:44.35, Dec= -27:32:26.9. We note that, within our current astrometric errors this source is positionally coincident with with the bright galaxy identified as Source D by Bloom et al. (GCN#3672). Based on background source counts, we expect 0.02 sources per square arcminute above this brightness (~170 uJy). Further observations are planned to determine the nature of this radio source.
