TITLE: GCN CIRCULAR NUMBER: 45052 SUBJECT: The EP-WXT trigger 01709272671 is likely a flaring star DATE: 26/06/28 02:08:13 GMT FROM: EP Team at NAOC/CAS <ep_ta@bao.ac.cn> J. P. Chen (SYSU), K. J. Zhang, D. Zhu (YNU), Y. J. Yi (BNU), Z. X. Ling (NAO, CAS) on behalf of the Einstein Probe (EP) team: The EP-WXT trigger 01709272671 at the time of 2026-06-27T17:53:04 (UTC), is likely a stellar flare associated with RX J1942.2-2045. 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 4.8 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 X-ray follow-up capability (Yuan et al. 2022, Handbook of X-ray and Gamma-ray Astrophysics).
