The EP-WXT trigger (ID: 01709131290) on 2025-02-06 09:52:08 (UTC) is likely a stellar flare associated with a star UCAC4 185-006985. The estimated flux of the flare is around 1.9 x 10^-10 erg/s/cm^2 in 0.5-4.0 keV, corresponding to an X-ray luminosity of around 5.5 x 10^31 erg/s.

Launched on January 9, 2024, EP is a space X-ray observatory to monitor the soft X-ray sky with onboard X-ray follow-up capability (Yuan et al. 2022, Handbook of X-ray and Gamma-ray Astrophysics).
