We observed the position of the reported GW190426c afterglow candidate: ZTF19aassfws (D. A. Perley et al. GCN 24331) with the AMI Large Array at a central frequency of 15.5GHz. We started observing on 2019 May 10.16 for 4 hrs. We find no significant radio emission at the coordinates of ZTF19aassfws and therefore report a 3 sigma upper limit of 177uJy.
We thank the MRAO staff for scheduling these observations.
