TITLE: GCN CIRCULAR NUMBER: 19608 SUBJECT: GRB 160601A: 15 GHz upper limits from AMI DATE: 16/06/28 13:09:02 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 160601A (Kocevski et al., GCN 19478) 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 Jun 01.78, Jun 02.95, Jun 04.95, and Jun 11.95 (UT) do not reveal any radio source at the XRT location (Evans et al., GCN 19484), with 3sigma upper limits of 282 uJy, 216 uJy, 108 uJy, and 132 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/.
