We observed the Fermi/LAT GRB 160623A (Vianello et al., GCN 19553) with 
the AMI Large Array at 15 GHz on 2016 Jun 25.15 and Jun 27.15 (UT), 2.0 
and 4.0 days post-burst, as part of the 4pisky program. We detect an 
uncataloged variable radio source at the XRT location (Mingo et al., GCN 
19558) at 5.0+/-0.1 mJy and 6.3+/-0.1 mJy (preliminary) respectively.

Monitoring of this source is underway. 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
