TITLE: GCN CIRCULAR NUMBER: 19508 SUBJECT: GRB 160408A: 15 GHz upper limits from AMI DATE: 16/06/08 15:12:47 GMT FROM: Kunal Mooley at Oxford U K. P. Mooley, T. D. Staley, R. P. Fender (Oxford), G. E. Anderson (Curtin), T. Cantwell (Manchester), C. Rumsey, D. Titterington, S. Carey, J. Hickish, Y. C. Perrott, N. Razavi-Ghods, P. Scott (Cambridge), K. Grainge, A. Scaife (Manchester) The AMI Large Array robotically triggered on the Swift alert for GRB 160408A (Evans et al., GCN 19260) as part of the 4pisky program, and subsequent follow up observations were obtained up to 10 days post-burst. Our observations at 15 GHz on 2016 Apr 08.61, Apr 09.77, Apr 13.87, Apr 15.74, and Apr 19.78 (UT) do not reveal any radio source at the XRT location (Osborne et al., GCN 19261), with 3sigma upper limits of 117 uJy, 144 uJy, 102 uJy, 204 uJy, and 145 uJy respectively. We thank the AMI staff for scheduling these observations. The AMI-GRB database is a log of all GRB follow up observations with the AMI, and is available at http://4pisky.org/ami-grb/.
