TITLE: GCN CIRCULAR NUMBER: 38127 SUBJECT: EP241107a: GSP detects optical counterpart DATE: 24/11/08 11:20:01 GMT FROM: Wenxiong Li liwenxiong1992@gmail.com
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: 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.
