Malesani (DAWN/NBI and Radboud) report on behalf of a larger collaboration:\n\nWe conducted follow-up observations of GRB 260515A (Brunet et al., GCN 44622) with the IO:O camera on the 2m robotic Liverpool Telescope (LT). Observations began at 22:42:40 UT on 2026-05-15,  ~3.57 hr after the burst, and consisted of 5 x 200 s exposures in each of the SDSS g and i filters.\n\nWe detect the optical counterpart (He et al., GCN 44623; Saccardi et al., GCN 44624; Sosnovskij et al., GCN 44625; He et al., GCN 44626; Wu et al., GCN 44628, Dennefeld et al., GCN 44633; Li et al., GCN 44634, Antier et al., GCN 44643) in both filters, and measure an AB magnitude of g = 21.06 ± 0.04.\n\nMagnitudes are calibrated against nearby Pan-STARRS stars and are not corrected for Galactic extinction.\n",
