TITLE: GCN CIRCULAR NUMBER: 41217 SUBJECT: The EP-WXT trigger 01709198202 is likely a flaring star DATE: 25/08/02 13:43:18 GMT FROM: EP Team at NAOC/CAS ep_ta@bao.ac.cn

The EP-WXT trigger 01709198202 at the time of 2025-08-02T12:44:54, is likely a stellar flare associated with BD-08 6022. The estimated flux of the flare is around 8.0 x 10^-11 erg/s/cm^2 in 0.5-4.0 keV. The autonomous follow-up observation with the Follow-up X-ray Telescope (FXT) detected a source at R.A. = 346.4735, DEC = -7.7644 deg (J2000) with an uncertainty of 20 arcsec in radius (90% C.L. statistical and systematic) within the WXT error circle, whose position is 10.2 arcsec away from the Eclipsing Binary BD-08 6022.
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).
