The AMI Large Array triggered on the Swift alert for GRB 170101A (Lien 
et al., GCN 20349) as part of the 4pisky program, and follow up 
observations were obtained up to 10 days post-burst. Our observations at 
15 GHz on 2016 Jan 03.33, Jan 04.45, Jan 05.46 and Jan 07.45 (UT) do not 
reveal any radio source in the BAT error circle (Barthelmy et al., GCN 
20353), with 3sigma upper limits of 105 uJy, 132 uJy, 78 uJy and 120 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/.
