Zhang (NAO,CAS) on behalf of the Einstein Probe (EP) team:\n\nEP-FXT performed a follow-up observation of the SVOM/ECLAIRs-detected burst GRB 260918A (SVOM/sb26091801; Zhao et al., GCN 45619) starting at 2026-09-18T05:52:20 UTC, approximately 2 hours after the SVOM trigger, with a total exposure time of 3004 s. Four uncataloged sources are detected within the ECLAIRs error circle. Preliminary analysis on these sources is automatically conducted, and the details are listed as follows.\n\nEPF_J233857.5-085504\nRA (J2000): 354.7406\nDec (J2000): -8.9179\nFlux: 1.3736 x 10^-13 erg/s/cm2 (observed, 0.5-10 keV)\nFlux_err: 2.7412 x 10^-14 erg/s/cm2 (1 sigma)\n\nEPF_J233915.3-084941\nRA (J2000): 354.8139\nDec (J2000): -8.8279\nFlux: 7.3429 x 10^-14 erg/s/cm2 (observed, 0.5-10 keV)\nFlux_err: 2.0415 x 10^-14 erg/s/cm2 (1 sigma)\n\nEPF_J233943.4-085235\nRA (J2000): 354.9304\nDec (J2000): -8.8773\nFlux: 4.3974 x 10^-13 erg/s/cm2 (observed, 0.5-10 keV)\nFlux_err: 6.4445 x 10^-14 erg/s/cm2 (1 sigma)\n\nEPF_J233833.8-090039\nRA (J2000): 354.6402\nDec (J2000): -9.0102\nFlux: 1.533 x 10^-13 erg/s/cm2 (observed, 0.5-10 keV)\nFlux_err: 3.6492 x 10^-14 erg/s/cm2 (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).",
