The\nobservation was done on 16 December 2022 from 15:17:47 to 15:32:55 (UT), 4.1\nhours after the GRB trigger. We obtained multiple 180-sec exposures in Ic\nfilter. We did not detect any afterglow within XRT localization (Evans et\nal., GCN 33071). This is consistent with the reported non-detections of (Lu\net al., GCN 33068) and (Gendre et al., GCN 33069).\n\n \n\nThe following upper limit was calculated using Atlas catalogue as a\nreference:\n\n----------------------------------------------------------------------------\n-\n\nJD (mid), T_mid-T0(hrs), Exposure (sec), Filter, Lim_mag\n\n----------------------------------------------------------------------------\n-\n\n2459930.142604, 4.1, 5 x 180 (stacked), Ic, > 17.3\n\n----------------------------------------------------------------------------\n-\n\n \n\nThese magnitudes are not corrected for galactic extinction.",
