Jin (NAO,CAS) on behalf of the Einstein Probe (EP) team:\n\nThe EP-WXT trigger 01709319528 at the time of 2026-09-21T14:01:16, is likely a stellar flare associated with HD 224129 (High Proper Motion Star). The estimated flux of the flare is around 1 x 10^(-10) erg/s/cm^2 in 0.5-4.0 keV, corresponding to an X-ray luminosity of around 7.8 x 10^30 erg/s.\n\nLaunched on January 9, 2024, EP is a space X-ray observatory to monitor the soft X-ray sky with X-ray follow-up capability (Yuan et al. 2022, Handbook of X-ray and Gamma-ray Astrophysics).",
