TITLE: GCN CIRCULAR NUMBER: 19564 SUBJECT: GRB 160525B: 15 GHz upper limits from AMI DATE: 16/06/24 12:53:04 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 160525B (Krimm et al., GCN 19459) 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 May 25.55, May 26.66, May 28.66, and May 31.68 (UT) do not reveal any radio source at the XRT location (Beardmore et al., GCN 19463), with 3sigma upper limits of 99 uJy, 63 uJy, 66 uJy, and 96 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/.
