Fu (HUST) report:\n\nWe observed the field of EP260417a detected by EP (Wang et. al, GCN 44325), using the 0.7-m telescope of the Thai Robotic Telescope network, located at Cerro Tololo Inter-American Observatory, Chile (TRT-CTO). We obtained a series of frames in the Sloan-r band.\n\nAn uncatalogued source is detected within the EP/WXT error circle at coordinates\nR.A. (J2000) = 16:21:17.47 (245.3228),\nDec. (J2000) = -22:01:26.31 (-22.0240)\nwith an uncertainty of ~ 1.0 arcsec. The source had r = 20.30 +/- 0.03 mag at a median time of ~ 7.92 hr post-trigger, calibrated with Pan-STARRS1 DR2 and not corrected for Galactic extinction.\n\nNo NEO would be at the above position at the observational time by checking MPC.\n\nWe thus think the source could be the optical counterpart of EP260417a.",
