TITLE: GCN CIRCULAR NUMBER: 39187 SUBJECT: The EP-WXT trigger 01709131290 is likely a flaring star DATE: 25/02/07 03:34:16 GMT FROM: EP Team at NAOC/CAS ep_ta@bao.ac.cn
M. J. Liu, D. Y. Li, M. H. Zhang, H. N. Yang (NAOC, CAS), Z. Y. Liu (USTC), Q. C. Shui (IHEP, CAS), W. D. Zhang, W. M. Yuan (NAOC, CAS) report on behalf of the Einstein Probe team:
The EP-WXT trigger (ID: 01709131290) on 2025-02-06 09:52:08 (UTC) is likely a stellar flare associated with a star UCAC4 185-006985. The estimated flux of the flare is around 1.9 x 10^-10 erg/s/cm^2 in 0.5-4.0 keV, corresponding to an X-ray luminosity of around 5.5 x 10^31 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).
