GRB 180418A: 15 GHz upper limits from AMI
Abstract
We observed the field of GRB 180418A (D'Elia et al., GCN 22646) with the AMI Large Array at 15.5 GHz. Our observations on 2018 Apr 18.88, Apr 20.89 and Apr 22.86 (UT) (0.61 d, 2.61 d and 4.58 post-burst) do not reveal any radio source at the XRT location (Goad et al., GCN 22650), with preliminary 3sigma upper limits of 99 uJy, 81 uJy and 93 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 at http://4pisky.org/ami-grb/.
