Scott (Cambridge), K. \nGrainge, A. Scaife (Manchester)\n\nThe AMI Large Array robotically triggered on the Swift alert for short \nGRB 170428A (Beardmore et al., GCN 21042) as part of the 4pisky program, \nand subsequent follow up observations were obtained up to 3 days \npost-burst. Our observations at 15 GHz on 2016 Apr 28.42 and Apr 30.34 \n(UT) do not reveal any radio source at the XRT location (Beardmore et \nal., GCN 21047), with 3sigma upper limits of 117 uJy and 96 uJy \nrespectively.\n\nWe thank the AMI staff for scheduling these observations. The AMI-GRB \ndatabase is a log of all GRB follow up observations with the AMI, and is \navailable at http://4pisky.org/ami-grb/.",
