TITLE: GCN CIRCULAR NUMBER: 44922 SUBJECT: The EP-WXT trigger 01709269176: SVOM/C-GFT confirmation of a stellar flare DATE: 26/06/12 09:14:55 GMT FROM: SVOM_group <svomgroup@bao.ac.cn> S.J.

Wei (NAOC) report on behalf of the SVOM/C-GFT team: We observed the field of EP-WXT trigger 01709269176 (Zhou et al., GCN 44913) with LATIOS on SVOM/C-GFT. Observations started at 2026-06-11T13:13:04.862 UTC, ~47.5 min after the trigger. Our observations in g,r and i bands confirmed that the reported associated star (GAIA DR3 1249275629854893952,GCN 44913 ) exhibits stellar flares. A flare is detected at ~5000 s post trigger, with an amplitude of ~1.3 mag in g-band and ~0.4 mag in i-band. The flare epoch is consistent with an X-ray flare detected by EP-FXT (EP team, private communication). The photometry was calibrated against nearby Pan-STARRS1 DR1 stars. We thank the observation assistants Chulei Guo and Yinhuai Hao at Jilin observatory for their excellent support. The Chinese Ground Follow-up Telescope (C-GFT) for the SVOM mission is located at Jilin Station, Changchun Observatory, National Astronomical Observatories, CAS. It features two instruments: (1) CATCH at the Cassegrain focus with a 21 arcmin x 21 arcmin FOV for simultaneous g/r/i-band imaging, and (2) LATIOS, a 4k x 4k CMOS camera at the prime focus with a 1.28 deg x 1.28 deg FOV that images in g, r, and i bands via filter switching.
