Pan(NAOC) on behalf of the Einstein Probe (EP) team:\n\nEP-FXT performed a follow-up observation of GRB 260818A detected by SVOM/ECLAIRs (Yin et al., GCN 45391). The observation started at 2026-08-18 02:43:32(UTC), about 1.67 hr after the SVOM trigger, with a total exposure time of around 4.6 ks.\n\nOn-ground analysis of the FXT data found several uncataloged sources inside the ECLAIRs error region. \nName | RA | DEC | Sep_obj (arcmin) | Flux (erg/cm^2/s)\nEPF_J232025.8-320549 | 350.1077 | -32.0971 |  6.101382 | 1.3205e-13\nEPF_J231936.3-320537 | 349.9012 | -32.0935 |  6.582593 | 5.9746e-14\nEPF_J231953.3-320838 | 349.9729 | -32.1449 |  6.812141 | 2.0801e-13\nEPF_J231912.9-320034 | 349.8036 | -32.0095 | 10.701601 | 1.0260e-12\nEPF_J231953.3-320838 | 349.9722 | -32.1440 |  6.770902 | 2.0112e-13\nEPF_J232037.7-320633 | 350.1572 | -32.1093 |  8.604395 | 4.5878e-14\nwith uncertainties of 10 arcsec (radius, 90% C.L. statistical and systematic). \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).",
