The AMI Large Array robotically triggered on the Swift alert for GRB 
170202A (Racusin et al., GCN 20575) 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 2016 Feb 02.87, Feb 04.00, Feb 
06.04, Feb 07.01 and Feb 09.00 (UT) do not reveal any radio source at 
the XRT location (Osborne et al., GCN 20586), with 3sigma upper limits 
of 451 uJy, 69 uJy, 81 uJy, 352 uJy and 105 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/.
