TITLE: GCN CIRCULAR NUMBER: 18947 SUBJECT: GRB 160127A: VLA Detection DATE: 16/01/29 02:54:28 GMT FROM: Kate Alexander at Harvard K. D. Alexander (Harvard), T. Laskar (NRAO / UC Berkeley), and E. Berger (Harvard) report on behalf of a larger collaboration: We observed GRB 160127A (Amaral-Rogers et al., GCN 18938) at multiple frequencies with the Karl G. Jansky Very Large Array (VLA) beginning 2016 January 28.46 UT (1.09 days after the burst). At a mean frequency of 21.8 GHz, we detect a radio source with a preliminary flux density of ~70 uJy at RA = 15:03:55.773 +/- 0.013 Dec = +00:04:22.07 +/- 0.17 consistent with the enhanced Swift/XRT position (Evans et al., GCN 18940) and the optical position (Cucchiara et al., GCN 18941; Siegel & Amaral-Rogers, GCN 18945). Follow-up observations are planned. We thank the VLA staff for rapidly executing these observations.
