S.-F. Zhu (USTC), H. Zhou (PMO, CAS), R. D. Liang (NAO, CAS), Z. X. Ling (NAO, CAS) report on behalf of the Einstein Probe team:

The EP-WXT trigger (ID 01709129023) on 2024-12-16T09:39:05 (UTC) is likely a stellar flare associated with an eruptive variable UCAC4 797-019583. The estimated flux of the flare is around 1.8 x 10^-10 erg/s/cm^2 in 0.5-4 keV, corresponding to an X-ray luminosity of around 6 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).
