Sun (NAO, CAS) report on behalf of the Einstein Probe team\n\nWe performed a follow-up observation of  EP260119a (detected by EP-WXT  Jiang et al ., GCN #43447 ), with the Follow-up X-ray Telescope (FXT) on board the Einstein Probe (EP) mission. The observation began at 2026-01-19T07:21:31 UTC, about 7 hours after the detection.\n\nThe FXT onboard alert shows that one uncatalogued source was detected by both FXT-A and FXT-B. The position of the source is R.A. = 158.1047 deg, DEC = 65.4975 deg, (J2000) with an uncertainty of 20 arcsec in radius (90% C.L. statistical and systematic). The estimated flux in the 0.5-10 keV band inferred from the alert information is around 5.0 x 10^-13 erg/cm^2/s. \n\nMore 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). EP is a mission of the Chinese Academy of Sciences in collaboration with ESA, MPE and CNES.",
