W. Chen (NAO, CAS) , Q. C. Shui (IHEP, CAS), H. He, S. K. Yang (WHU), C. C. Jin (NAO, CAS) report on behalf of the Einstein Probe team:
The EP-WXT trigger (ID 01709129925) on 2025-01-05 20:53:30 (UTC) is likely a stellar flare associated with a High Proper Motion Star 1RXS J060224.9-163451. 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 2 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).
