TITLE: GCN CIRCULAR NUMBER: 39351 SUBJECT: The EP-WXT trigger 01709131775 is likely a flaring star DATE: 25/02/17 08:09:25 GMT FROM: EP Team at NAOC/CAS ep_ta@bao.ac.cn
C. Zhou (HUST), G. Y. Zhao (SYSU), T. C. Zheng (PMO, CAS), X. Pan, H. W. Pan (NAOC, CAS) report on behalf of the Einstein Probe team:
The EP-WXT trigger (ID: 01709131775 ) on 2025-02-17 06:56:23 (UTC) is likely a stellar flare associated with a T Tauri star RX J0523.0-0850. The estimated flux of the flare is around 8.0 x 10^-11 erg/s/cm^2 in 0.5-4.0 keV, corresponding to an X-ray luminosity of around 2.2 x 10^32 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).
