TITLE: GCN CIRCULAR NUMBER: 36832 SUBJECT: EP240703a: TRT further optical observation DATE: 24/07/05 15:25:25 GMT FROM: S. Tinyanont at National Astronomical Research Institute of Thailand <samaporn@narit.or.th> S. Tinyanont, R. Anutarawiramkul, P. Butpan (NARIT), X. Liu, S.Q. Jiang, J. An, S.Y. Fu, Z.P. Zhu, D. Xu, Z. Fan, W.X. Li, N.C. Sun, Y.N. Wang (NAOC) report on behalf of a large collaboration: We observed the field of the fast X-ray transient EP240703a (Wang et al., GCN 36807) using the 0.7-m telescope of the Thai Robotic Telescope (TRT) network, located at Spring Brook Observatory, Australia. Observations started at 10:16:15 UTC on 2024-07-04, i.e., 1.40 day after the EP trigger, and 5 x 360 s I-band frames were obtained. No uncatalogued optical transient is detected in the stacked image within the 3-arcmin EP/WXT error circle, down to a 5-sigma limiting magnitude of I ~ 20.0, calibrated with Pan-STARRS sources in the field.
