W. X. Li, S. J. Xue, D. Xu (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 EP240408a by the Einstein Probe (Hu et al. GCN 36053), we initiated observations of the fast X-ray transient location starting on April 9 at 10:46 UT (~17 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 Siding Spring Observatory in Australia.
We report that no new optical source was detected in the co-added images within the EP/WXT error box down to ~21.5 mag.
These observations were taken as part of the Global Supernova Project.
