Observations in the g/i/r bands began at 2026-10-29T12:26:03, approximately 10.98 hours after the trigger.\n \nWe clearly detect the optical counterpart (O'Neill et al. GCN 46073; He et al. GCN 46078; Wang et al. GCN 46079; Cotter et al. GCN 46081; Álvarez et al., GCN 46083; Yin et al., GCN 46084; Shi et al., GCN 46088; Kang et al., GCN 46090; Ma et al., GCN 46092.; De et al., GCN 46093) in the images. The g-band photometry result is presented in the following : \n \nMJD | exposure time (s) | band |  mag (AB) \n-------------|-------------------|------|---------------\n    61342.56469907407     |         120        | g |  20.73+/-0.02    \n \nWe thank the WFST staff for supporting these observations.\n\n",
