The AMI Large Array robotically triggered on the Swift alert for GRB
170711A (D'Elia et al., GCN 21321) 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 12.14, Jul 13.38, Jul
16.29 and Jul 20.36 (UT) do not reveal any radio source at the XRT
location (Beardmore et al., GCN 21323), with 3sigma upper limits of 186
uJy, 96 uJy, 102 uJy and 183 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/.
