We observed the GRB 170307A detected by Swift (Lien et al., GCN 20832, 
Stamatikos et al. GCN 20838) and Fermi (Hui et al. GCN 20835) with the 
AMI Large Array at 15 GHz on 2016 Mar 13.57 (UT). We place a 3sigma 
upper limit of 90 uJy on the radio afterglow.

We thank the AMI staff for scheduling this observation. 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/.
