A. Li (BNU), M. Q. Huang, Z. Y. Liu (USTC), W. J. Zhang, Y. Liu (NAO,CAS) report on behalf of the Einstein Probe team:

The EP-WXT trigger (ID 01709128921) on 2024-12-15 08:43:05.749 (UTC) is likely a stellar flare associated with a double or multiple star RX J0413.4-0139. The estimated flux of the flare is around 2.0 x 10^-10 erg/s/cm^2 in 0.5-4 keV, corresponding to an X-ray luminosity of around 1.7 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).
