Scaife (Manchester) The AMI Large Array robotically triggered on the Swift alert for GRB 160917A (Racusin et al., GCN 19926) 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 Sep 17.65, Sep 20.87, and Sep 24.87 (UT) do not reveal any radio source at the XRT location (Evans et al., GCN 19927), with 3sigma upper limits of 150 uJy, 84 uJy, and 90 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/.
