Q. Y. Wu, D. H. Zhao (NAO, CAS), C. Y. Dai (NJU), Y. C. Fu (BNU), C. X. Zhang (HUST), Y. Liu (NAO,CAS) report on behalf of the Einstein Probe team:

The EP-WXT trigger on 2024-11-16T07:42:57.649 (UTC), with the GCN Notice ID 01709120856, is likely a stellar flare associated with a double or multiple star system BPS CS 31060-0015. The estimated flux of the flare is around 8 x 10^-11 erg/s/cm^2 in 0.5-4 keV, corresponding to a X-ray luminosity of around 3 x 10^30 erg/s, which is a typical value for a M-type dwarf. 

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).
