Q. C. Liu (THU), W. Chen, X. Mao, Z. X. Ling (NAO, CAS) report on behalf of the Einstein Probe team:

The EP-WXT trigger (ID 01709128948) on 2024-12-23 09:22:35 (UTC) is likely a stellar flare associated with a High Proper Motion Star TYC 5360-423-1. The estimated flux of the flare is around 2 x 10^-11 erg/s/cm^2 in 0.5-10.0 keV, corresponding to an X-ray luminosity of around 5 x 10^31erg/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).
