The AMI Large Array robotically triggered on the Swift alert for GRB
170714A (D'Ai et al., GCN 21340) 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 2017 Jul 15.11, Jul 18.27, Jul
20.23 and Jul 22.25 (UT) do not reveal any radio source at the XRT
location (Evans et al., GCN 21341), with 3sigma upper limits of 279 uJy,
172 uJy, 288 uJy and 210 uJy respectively. These upper limits are
consistent with the results from previously-reported radio observations
(Horesh et al., GCN 21352; Ricci et al., GCN 21360; Piro et al., GCN
21424).
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
