The EP-WXT trigger 01709176712 at the time of 2025-05-23T12:44:31, is likely a stellar flare associated with Gaia DR3 6277472183485764992 (R.A., DEC. = 213.94224, -21.58397 deg.). The estimated flux of the flare is around 8e-11 erg/s/cm^2 in 0.5-4.0 keV, corresponding to an X-ray luminosity of around 2.5e+33 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).
