TITLE: GCN CIRCULAR NUMBER: 36590 SUBJECT: LXT 240528A: GSP optical upper limit DATE: 24/06/01 11:45:21 GMT FROM: Wenxiong Li <liwenxiong1992@gmail.com> 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 LXT 240528A by the Lobster Eye Imager for Astronomy (LEIA) (Lian et al. GCN 36567), we initiated observations of the transient's location in the g and r bands on May 30 at 3:39 UT, ~39 hours after the trigger. These observations were conducted using the 1-meter telescope at the Las Cumbres Observatory node located at Tenerife in Spain. We report that no new optical source was detected in the co-added images within the error box down to a limiting magnitude of ~22.0. These observations were taken as part of the Global Supernova Project.
