Dimple (U. Birmingham), A. Martin-Carrillo (UCD), D. B. Malesani (DAWN/NBI and Radboud), D. O’Neill (U. Birmingham), and B. P. Gompertz (U. Birmingham) report on behalf of a larger collaboration:

We conducted the observations of GRB 261113A (Saccardi et al., GCN 46244), with the IO:O optical camera on the 2-m robotic Liverpool Telescope in the r, i, and z filters starting on 2026-11-13 at 22:25:40 UT (7.9 hr after the burst) and continued until 2026-11-14 at 00:33:14 UT. We clearly detected the optical counterpart (Lin et al., GCN 46247; 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; Zhao et al., GCN 46253; Li et al., GCN 46254; Saikia et al., GCN 46256; Adami et al., GCN 46257; Gress et al., GCN 46258; Izzo et al., GCN 46259; Brivio et al., GCN 46260; Maksut et al., GCN 46262; Moskvitin et al., GCN 46263; Perez-Garcia et al., 46264) in all the bands with 21.59 +/- 0.05 and 21.74 +/- 0.34 in r and z, respectively.

Magnitudes are calibrated against nearby Pan-STARRS stars and are not corrected for Galactic extinction.
