TITLE: GCN CIRCULAR NUMBER: 39188 SUBJECT: The EP-WXT trigger 01709131332 is likely a flaring star DATE: 25/02/07 03:50:53 GMT FROM: EP Team at NAOC/CAS <ep_ta@bao.ac.cn> M. H. Zhang, M. J. Liu, D. Y. Li (NAOC, CAS), Q. C. Shui (IHEP, CAS), W. D. Zhang (NAOC, CAS) report on behalf of the Einstein Probe team: The EP-WXT trigger (ID: 01709131332) on 2025-02-06 20:25:17 (UTC) is likely a stellar flare associated with a high proper motion star UPM J1217-3644. The estimated flux of the flare is around 1.2 x 10^-10 erg/s/cm^2 in 0.5-4.0 keV, corresponding to an X-ray luminosity of around 1.2 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).
