Following the detection of the fast X-ray transient EP241107a by the Einstein Probe (Zhou et al., GCN 38112) with the Sinistro instrument mounted on the 1-m telescope of the LCO, we initiated observations of the fast X-ray transient location starting on 2024 November 7 at 19:13 UT (~5 hours after the EP/WXT trigger) in the i band. These observations were conducted using the 1-meter telescope at the Las Cumbres Observatory node located at Sutherland in South Africa.
The optical counterpart (Odeh et al., GCN 38115; Kang et al., GCN 38116; Mohan et al., GCN 38118; Busmann et al., GCN 38120) was detected in the co-added images with i = 19.4+-0.1.
These observations were taken as part of the Global Supernova Project.
