The AMI Large Array robotically triggered on the Swift alert for GRB
170203A (Racusin et al., GCN 20583) 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 03.37, Feb 04.56, Feb
06.56 and Feb 10.55 (UT) do not reveal any radio source at the BAT
location (Cummings et al., GCN 20597), with 3sigma upper limits of 183
uJy, 84 uJy, 75 uJy and 171 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/.
