J. An, D. Xu, W. X. Li, S. J. Xue (NAOC), M. Andrews, J. Farrah, D. A. Howell, M. Newsome, E. Padilla Gonzalez, C. McCully, and G. Terreran (Las Cumbres Observatory), on behalf of a larger collaboration, report: Following the detection of the fast X-ray transient EP240801a by the Einstein Probe (Zhou et al., GCN 36997), we initiated observations of the fast X-ray transient location starting on Aug 1 at 10:26 UT (~1.3 hours after the trigger) in the r band. These observations were conducted using the 1-meter telescope at the Las Cumbres Observatory node located at McDonald Observatory in the USA. The optical counterpart reported by Fu et al. (GCN 36998), Li et al. (GCN 36999) and Zheng et al. (GCN 37000) was detected with r = 20.54+/-0.08 mag. These observations were taken as part of the Global Supernova Project.
