TITLE: GCN CIRCULAR NUMBER: 36592 SUBJECT: GRB 240529A: AKO Optical Afterglow Follow-Up Observations DATE: 24/06/01 12:17:07 GMT FROM: Mohammad Odeh at Al Khatim Observatory M44 Mohammad Odeh (Al-Khatim Observatory, AKO, operated by the International Astronomical Center in Abu Dhabi, UAE), Nidhal Guessoum, Dalya Akl, Ilmah Aabdi, and Shaikha AlShamsi (American University of Sharjah, UAE), report: As a follow-up to our first observation performed on May 29, 2024 (GCN 36573 ), we report further observations of the field of GRB 240529A (Eyles-Ferris et al., GCN 36556) with our 0.36m f/7.7 robotic telescope, on May. 30, starting at 22:09 UT. We obtained multiple 180-sec exposures in the Ic filter, where we marginally detected the GRB afterglow. Our detection is consistent with the results of (Kumar et al., GCN 36559; Fu et al., GCN 36561; Shilling et al., GCN 36562; Perez-Garcia et al., GCN 36563; Dutton et al., GCN 36568; Mo et al., GCN 36569; Odeh et al.
