TITLE: GCN CIRCULAR NUMBER: 19453 SUBJECT: GRB 160327A: 15 GHz upper limits from AMI DATE: 16/05/24 15:04:33 GMT FROM: Kunal Mooley at Oxford U K. P. Mooley, T. D. Staley, R. P. Fender (Oxford), G. E. Anderson (Curtin), 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 160327A (Racusin et al., GCN 19235) 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 Mar 27.75, Mar 28.94, Mar 30.94, Apr 04.79, and Apr 06.83 (UT) do not reveal any radio source at the XRT location (Goad et al., GCN 19237), with 3sigma upper limits of 84 uJy, 69 uJy, 96 uJy, 102 uJy, and 93 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/.
