Scaife (Manchester) The AMI Large Array robotically triggered on the Swift alert for GRB 170607A (D'Ai et al., GCN 21214) 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 08.12, Jun 10.29, Jun 12.28 and Jun 16.24 (UT) do not reveal any radio source at the XRT location (Beardmore et al., GCN 21215), with 3sigma upper limits of 318 uJy, 108 uJy, 117 uJy and 117 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/.
