The observations were initiated at 2026-11-13T16:06:31.98 (~1.59 hours after the trigger) with the 60cm Panzhihua Telescope located at the Sichuan South Observatory (SSO), China. Several frames with 300s exposure each were acquired in L band. \n\nWe clearly detect the optical counterpart (Lei et al., GCN 46248; Li et al., GCN 46249; Yin et al., GCN 46250; Chen et al., GCN 46251; Wu et al., GCN 46252) in the stacked image. The L-band preliminary photometric magnitudes are following:\n\nMJD (Exp_Start)\t      MAG                      FILTER              EXPTIME\n61357.671203          20.18 +/- 0.13           L                   5 x 300s\n61357.690732          20.44 +/- 0.19           L                   5 x 300s\n\nNote that the expected Galactic extinction is not applied in our estimates.\n\n\n",
