TITLE: GCN CIRCULAR NUMBER: 22014 SUBJECT: GRB 171010A: VLA Detection DATE: 17/10/13 20:55:59 GMT FROM: Tanmoy Laskar at UC Berkeley T. Laskar (NRAO / UC Berkeley), D. L. Coppejans, and R. Margutti (Northwestern University) report on behalf of a larger collaboration: "We observed GRB 171010A (Omodei et al.; GCN 21985) at multiple frequencies with the VLA beginning on 2017 October 13.32 UT (2.79 days after the burst). At a mean frequency of 6 GHz, we detect a radio source with a preliminary flux density of ~ 0.7 mJy at RA = 04:26:19.4780 +/- 0.0005 Dec = -10:27:46.03 +/- 0.01 consistent with the Swift/XRT position (D'Ai et al.; GCN 21989) and the optical position (Halpern et al.; GCN 21987, Izzo et al.; GCN 21988). Follow-up observations are planned. We thank the VLA staff for rapidly scheduling these observations."
