We observed the INTEGRAL/IBIS GRB 160521A (Mereghetti et al., GCN 19442) 
with the AMI Large Array at 15 GHz on 2016 May 24.62, May 27.52, and Jun 
03.61 (UT) as part of the 4pisky program. We detect a transient radio 
source (RA=08:38:51.3 +/-6 arcsec, Dec=+46:54:21 +/-24 arcsec) within 
the INTEGRAL error circle at 266+/-36 uJy and 133+/-29 uJy in the first 
two epochs, and obtain a 3sigma upper limit of 93 uJy in the third epoch.

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/.
