Ling (NAO, CAS) on behalf of the Einstein Probe (EP) team:\n\nWe report on the detection of an X-ray transient by the Wide-field X-ray Telescope (WXT) on board the Einstein Probe (EP) mission, designated EP260610b. The transient triggered EP-WXT (ID: 01709268876) at 2026-06-10T12:48:17 (UTC). The WXT position of the source is R.A. = 267.601 deg, DEC = 46.534 deg (J2000) with an uncertainty of 3 arcmin in radius (90% C.L. statistical and systematic).\n\nA follow-up observation with the Follow-up X-ray Telescope (FXT) was performed automatically. Within the WXT error circle, an uncatalogued X-ray source was detected at R.A. = 267.6268 deg, DEC = 46.5388 deg (J2000) with an uncertainty of 20 arcsec in radius (90% C.L. statistical and systematic).\n\nFurther information will be updated when the telemetry data is received.\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).\n",
