GCN-45382 — The EP-WXT trigger 01709279838 is likely a flaring star
· Fri, 14 Aug 2026 13:20:54 GMT
The Einstein Probe (EP) detected a likely stellar flare from the star PM J22403-4931 on 2026-08-14, with an estimated flux of 1.6 x 10^-10 erg/s/cm^2 in the 0.5-4.0 keV range, corresponding to an X-ray luminosity of around 2.7 x 10^30 erg/s. This detection is significant as it demonstrates the EP's capability to monitor and detect soft X-ray events in the sky.
