The EP-WXT trigger 01709322274 at the time of 2026-11-06T21:28:37, is likely a stellar flare associated with a high proper motion M dwarf Gaia DR3 111731654357442816. The estimated flux of the flare is around 6e-11 erg/s/cm^2 in 0.5-4.0 keV, corresponding to an X-ray luminosity of around 3.6e29 erg/s.
