The AMI Large Array observed the Swift GRB 170206B (Lien et al., GCN
20618) as part of the 4pisky program; follow up observations were
obtained up to 10 days post-burst. Our observations at 15 GHz on 2016
Feb 08.37, Feb 09.38, Feb 14.43 and Feb 15.46 (UT) do not reveal any
radio source at the XRT location (Evans et al., GCN 20619), with 3sigma
upper limits of 123 uJy, 108 uJy, 108 uJy and 108 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/.
