W. X. Li, S. J. Xue (NAOC), M. Andrews, J. Farah, D. A. Howell, M. Newsome, E. Padilla Gonzalez, C. McCully, and G. Terreran (Las Cumbres Observatory), on behalf of a larger collaboration, report the optical follow-up observations of the fast X-ray transient EP240806a (Wu et al. 37063).

An uncatalogued source is detected in the individual as well as the stacked frames within the EP/FXT error circle and localized at coordinates

R.A. (J2000) = 11.4862 deg
Dec. (J2000) = 5.0945 deg
with an uncertainty of ~ 0.5 arcsec. The source has i ~ 21 mag, calibrated with SDSS and not corrected for Galactic extinction. There is no known object at the above position by checking MPC.
We thus conclude that the source is the optical counterpart candidate of EP240806a.
These observations were taken as part of the Global Supernova Project.
