W. X. Li, S. J. Xue, H. Sun (NAOC), X. F. Wang (THU), 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 the optical follow-up observations of AT2024gsa (Aryan et al., GCN 36094, Xu et al., GCN 36105, Srivastav et al. GCN 36150). This transient was identified as the optical counterpart to the fast X-ray transient EP240414a (Lian et al., GCN 36091; Guan et al., GCN 36129).
Our observations were conducted on 2024 April 18.065 UT using the 1-meter telescope at the Las Cumbres Observatory node located at Cerro Tololo Interamerican Observatory in Chile. AT2024gsa is detected in all BVgri band images.
The photometric results are:
B ~ 21.3m
V ~ 20.9m
g ~ 21.1m
r ~ 20.7m
i ~ 20.6m
Further followup observations are encouraged.
These observations were taken as part of the Global Supernova Project.
