D. Y. Li (NAOC, CAS), Q. C. Shui (IHEP, CAS), M. Q. Huang (UCST), Y. Liu (NAOC, CAS) report on behalf of the Einstein Probe team:
The EP-WXT trigger (ID: 01709132801) on 2025-03-16T07:30:48.149 (UTC) is likely a stellar flare associated with the low mass star LP 368-98 or LP 368-99. 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 2.0 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).
