Scaife (Manchester) The AMI Large Array robotically triggered on the Swift alert for GRB 160703A (Cenko et al., GCN 19645) as part of the 4pisky program, and subsequent follow up observations were obtained up to 10 days post-burst. While the first observation on 2016 Jul 03.83 was severely affected by RFI, our observations at 15 GHz on 2016 Jul 04.99, Jul 07.00, and Jul 11.00 (UT) do not reveal any radio source at the XRT location (D'Elia et al., GCN 19655), with 3sigma upper limits of 150 uJy, 210 uJy, and 120 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/.
