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/.
