The EP-WXT trigger 01709262036 at the time of 2026-05-13 08:45:48 (UTC), is likely a stellar flare associated with LP 497-99. The estimated flux of the flare is around 1×10^(-10) erg/s/cm^2 in 0.5-4.0 keV, corresponding to an X-ray luminosity of around 3.5×10^31 erg/s. Launched 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).
