P. \nFender (Oxford)\n\nWe observed the field of GRB 180418A (D'Elia et al., GCN 22646) with the \nAMI Large Array at 15.5 GHz. Our observations on 2018 Apr 18.88, Apr \n20.89 and Apr 22.86 (UT) (0.61 d, 2.61 d and 4.58 post-burst) do not \nreveal any radio source at the XRT location (Goad et al., GCN 22650), \nwith preliminary 3sigma upper limits of 99 uJy, 81 uJy and 93 uJy \nrespectively.\n\nWe thank the MRAO staff for scheduling these observations. Results from \nthe AMI short-GRB program are posted on the AMI-GRB database available \nat http://4pisky.org/ami-grb/.",
