Xu (NAOC) report on behalf of a large collaboration:\n\nWe observed the field of EP241021a detected by Einstein Probe (EP, Hu et al., GCN 37834) using the 0.7-m telescope of the Thai Robotic Telescope network (TRT), located at Fresno, California, US. Observations started at 09:14:23.699 UTC on 2024-10-22, i.e., 1.17 days after the EP trigger, and a series of 300 s frames were obtained in R- and V- bands.\n\nThe uncatalogued source reported by NOT (Fu et al., GCN 37840) is marginally detected in our stacked R- and V- band images, with R ~ 21.6 and V ~ 21.7, calibrated with Legacy-DR10 stars in the field and not corrected for Galactic extinction.",
