TITLE: GCN CIRCULAR NUMBER: 18977 SUBJECT: GRB 160131A: VLA detection DATE: 16/02/02 21:22:19 GMT FROM: Tanmoy Laskar at UC Berkeley T. Laskar (NRAO / UC Berkeley), K. D. Alexander, and E. Berger (Harvard) report on behalf of a larger collaboration: "We observed GRB 160131A (Page & Barthelmy; GCN 18951) at multiple frequencies with the Karl G. Jansky Very Large Array (VLA) beginning on 2016 February 01.11 UT (0.76 days after the burst). At a mean frequency of 21.8 GHz, we detect a radio source with a preliminary flux density of ~ 0.53 mJy at RA = 15:12:40.351 +/- 0.001 Dec = -07:02:58.80 +/- 0.02 consistent with the enhanced Swift/XRT position (Goad et al.; GCN 18958) and the optical position (Page & Barthelmy.; GCN 18951, Yurkov et al.; GCN 18952). Follow-up observations are planned. We thank the VLA staff for rapidly scheduling these observations."
