R.-Z. Li (YNAO, CAS), X.-L. Chen, K. Chatterjee (YNU) and H. Q. Cheng, Z. X. Ling (NAOC, CAS) report on behalf of the Einstein Probe team:
The EP-WXT trigger (ID 01709130111) on 2025-01-10 04:52:13 (UTC) is likely a stellar flare associated with a Low-mass Star RX J0429.3-3124. The estimated flux of the flare is around 1.6 x 10^-10 erg/s/cm^2 in 0.5-4.0 keV, corresponding to an X-ray luminosity of around 5.5 x 10^30 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).
