Xu (NAOC) report:\n\nWe observed the field of EP260707a detected by EP (Zhou et al., GCN 45107) using the 0.7-m telescope of the Thai Robotic Telescope network (TRT), located at New South Wales, Australia (SBO). 4x300s frames in the R-band were obtained at a median time of 1.52 hr post-trigger.\n\nNo uncatalogued optical transient is detected in the stacked image within the EP/FXT error circle (Zhou et al., GCN 45107), down to a 5-sigma limiting magnitude of R ~ 21.0 (Vega), calibrated with Pan-STARRS DR2 stars in the field converted using Lupton (2005) equations and not corrected for Galactic extinction.",
