The observation was done on 04 December\n2022 from 15:05:55 to 15:18:02 (UT), 4.47 hours after the Swift trigger. We\nobtained multiple 180-sec exposures in Ic filter. We did not detect any\nafterglow within XRT localization. This is consistent with the reported\nnon-detections of (Lipunov et al., GCN 33018).\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\n2459918.134358, 4.47, 5 x 180 (stacked), Ic, > 17.7\n\n----------------------------------------------------------------------------\n-\n\n \n\nThese magnitudes are not corrected for galactic extinction.",
