TITLE: GCN CIRCULAR NUMBER: 20200 SUBJECT: GRB 161108A: 15 GHz upper limits from AMI DATE: 16/11/21 18:19:57 GMT FROM: Kunal Mooley at Oxford U K. P. Mooley, T. D. Staley, R. P. Fender (Oxford), G.

Scaife (Manchester) The AMI Large Array robotically triggered on the Swift alert for GRB 161108A (Beardmore et al., GCN 20145) 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 Nov 08.19, Nov 09.40, Nov 12.35 and Nov 15.36 (UT) do not reveal any radio source at the XRT location (Beardmore et al., GCN 20147), with 3sigma upper limits of 378 uJy, 284 uJy, 190 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/.
