We obtained exposures in\nthe B, V, and Ic filters and did not detect any afterglow within XRT\nlocalization (Lien et al., GCN 32874). This is consistent with the reported\nnon-detections of (Hu et al., GCN 32878; Lipunov et al., GCN 32879;\nStrausbaugh et al., GCN 32881; Niwano et al., GCN 32883; Kumar et al., GCN\n32886; Watson et al., GCN 32888; Belkin et al., GCN 32889).\n\n\n\nEach image consists of seven stacked frames, each frame is a 3-minute\nexposure. The obtained upper limits are as follows:\n\n\n\nMid Time (UT), Filter, Lim. Mag.\n\n2022-10-30T16:16:06Z, B, > 18.3\n\n2022-10-30T16:13:03Z, V, > 19.6\n\n2022-10-30T16:09:22Z, Ic, > 20.2",
