Our limits\nare consistent with those reported in Lupinov et al. (GCN 23816) at around\nthe same delta since the burst.\n\nWe see no evidence for the source candidates reported by Bolmer et al.\n(GCN 23814), Piranomonto et al. (GCN 23818) and Butler et al. (GCN 23820).\n\n\nGOTO is operated at the La Palma observing facilities of the\nUniversity of Warwick on behalf of a consortium including the\nUniversity of Warwick, Monash University, Armagh Observatory, the\nUniversity of Leicester, the University of Sheffield, the National\nAstronomical Research Institute of Thailand (NARIT) and the Instituto\nde Astrofisica de Canarias (IAC) (https://goto-observatory.org/)",
