  "body": "Lauren Rhodes, Rob Fender (Oxford), Dave Green, Dave Titterington (Cambridge) report:\n \nWe observed the field of the afterglow candidate GRB 231117A (GCN 35071) with the Arcminute Microkelvin Imager Large-Array (AMI-LA) at 15.5 GHz beginning at UT 15:30:45 on 17-Nov-2023 for a total of 4 hours. The flux standard 3c286 was used to calibrate the bandpass response and flux scale of the AMI-LA and J2232+1143 was used as an interleaved complex gain calibrator.\n\nWe do not detect any radio emission at the position of the afterglow candidate as reported in GCN 35083 with a 3-sigma upper limit of 230uJy/beam. \n \nWe thank the staff at the Mullard Radio Astronomy Observatory for carrying out these observations and operating the AMI-LA.\n",
