A stellar flare was detected by the EP-WXT and confirmed by the BOOTES-5 telescope, which observed a star (ATO J336.9854+01.6911) decreasing in brightness by 0.18 magnitudes over 12 minutes, validating the X-ray trigger event.

GCN-46106 — The EP-WXT trigger 01709321980 is likely a flaring star · Fri, 30 Oct 2026 05:53:22 GMT
The Einstein Probe (EP) detected a likely stellar flare from ATO J336.9854+01.6911 on October 30, 2026, with an estimated flux of 8e-11 erg/s/cm^2 in the 0.5-4.0 keV range, corresponding to an X-ray luminosity of around 3.6e31 erg/s. This event is significant as it demonstrates the EP's capability to monitor and follow up on soft X-ray events in the sky.
