M. Q. Huang, Z. Y. Liu (USTC), Q. C. Shui (IHEP, CAS), H. N. Yang, Y. Liu (NAO, CAS) report on behalf of the Einstein Probe team:
The EP-WXT trigger (ID 01709128948) on 2024-12-15 20:23:50 (UTC) is likely a stellar flare associated with a young stellar object candidate ATO J079.4052-07.5576. The estimated flux of the flare is around (1.05 +- 0.02) x 10^-10 erg/s/cm^2 in 0.5-10.0 keV, corresponding to an X-ray luminosity of around (1.74 +- 0.03) x 10^33 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).
