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/.
