  "body": "J. Yang (ZZU), W. F. Wen (SZTU), R. C. Chen (NJU), T. Wu (AHNU), Z. X. Ling (NAO, CAS) on behalf of the Einstein Probe (EP) team:\n\nEP-FXT performed a follow-up observation of GRB 260914A, detected by SVOM/ECLAIRs and SVOM/GRM (sb26091401; Wang et al., GCN 45562), which was also observed in optical by SVOM/COLIBRÍ (Akl et al., GCN 45564), SVOM/VT (Palmerio et al., GCN 45565; Li et al., GCN 45566), SVOM/C-GFT (Shi et al., GCN 45567) and LCO (Saccardi et al., GCN 45568). The observation started at 2026-09-14 12:36:30 (UTC), about 1.4 hours after the SVOM/ECLAIRs trigger, with an exposure time of 6 ks.\n\nOn-ground analysis of the EP-FXT data found an uncataloged fading X-ray source within the SVOM/ECLAIRs error region (Wang et al., GCN 45562). The preliminary results for the X-ray source are as follows:\nSource name: EPF_J020623.5+291518\nR.A., Decl. (J2000) = 31.5979, 29.2548 deg\nLocalization error radius = 10 arcsec\n0.5-10 keV flux = 2.7e-12 erg/cm^ 2/s\nFlux error = 2.2e-13 erg/cm^2/s (1 sigma)\n\nLaunched 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).",
