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/.
