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 <mshodeh@gmail.com> 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 <https://gcn.nasa.gov/circulars/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.

The following table summarizes the results of the two nights, calculated using the Atlas catalog as a reference: ----------------------------------------------------------------- ObsTime (mid), Exposure, Filter, Mag, S/N, Lim. Mag. ----------------------------------------------------------------- 2024-05-29T23:08:00Z, 24 x 180s (stacked), Ic, 17.9 +/- 0.10, 16.1, 19.8 2024-05-30T23:15:55Z, 21 x 180s (stacked), Ic, 18.8 +/- 0.17, 8.0, 19.7 ----------------------------------------------------------------- The magnitudes are not corrected for galactic extinction.
