We observed the field of short GRB 180718A (Ukwatta et al., GCN 22947) 
with the AMI Large Array at 15 GHz. Our observations on 2018 Jul 16.80, 
Jul 17.73, Jul 19.80 and Jul 23.80 (UT) (1.05 d, 1.98 d, 4.05 d and 7.05 
d post-burst) does not reveal any potential afterglow candidate 
consistent with the BAT location (Ukwatta et al., GCN 22947), and our 
3sigma upper limit to the flux density are 137 uJy, 186 uJy, 106 uJy and 
146 uJy respectively.

We thank the MRAO staff for scheduling these observations. Results from 
the AMI Short GRB program are posted on the AMI-GRB database available
