Ling (NAOC, CAS) on behalf of the Einstein Probe (EP) team:\n\nFollowing the possible detection of the GRB 250510A (Cheng et al., GCN 40415) and its multi-wavelength follow-up observations (Antier et al., GCN 40417), we performed an observation with the Follow-up X-ray Telescope (FXT) on board the Einstein Probe mission. \n\nThe observations began at 2025-05-10T07:54:01 (UTC), about 3.3 hours after the SVOM-ECLAIRs detection. The exposure time is 4035 seconds. Preliminary analysis shows there are three source was detected in this epoch within the ECLAIRs error circle:\n------------------------------------------------------------------------------------------------------\n|    Source Name     |    RA   |   DEC   | Flux(erg/s/cm2) | Flux_err  |\n------------------------------------------------------------------------------------------------------\n|EPF_J185647.0+182414| 284.1957 | 18.4041 |     9.91e-14    |  3.41e-14 |\n------------------------------------------------------------------------------------------------------\n|EPF_J185624.3+182129| 284.1012 | 18.3581 |     1.07e-13    |  2.59e-14 |\n------------------------------------------------------------------------------------------------------\n|EPF_J185624.8+181937| 284.1033 | 18.3269 |     1.35e-13    |  2.92e-14 |\n------------------------------------------------------------------------------------------------------\n\nEP-FXT will continue monitoring the source. More follow-up observations are encouraged. \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).",
