Quirola-Vasquez (Radboud) report on behalf of a larger collaboration:\n\nWe observed the field of the fast X-ray transient EP260920b (Ni et al., GCN 45664; Yang et al., GCN 45670) using using an LCO 1m telescope located at the Cerro Tololo Interamerican Observatory (Chile) equipped with the SINISTRO instrument. We obtained 11x300 s exposures in the SDSS r-band starting at 2026-09-21 01:13:47 (~11.1 hours after the trigger).\n\nThe counterpart (Liu et al., GCN 45668; García-García et al., GCN 45669; Li et al., GCN 45671) is detected in our images at a magnitude of r = 21.38 +/- 0.13 at t_mid - t0 = 11.57 hours. Our photometry is calibrated using PanSTARRS and is not corrected for Galactic extinction.",
