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:
We observed the field of GRB 240529A (Eyles-Ferris et al., GCN 36556), with
our 0.36m f/7.7 robotic telescope. The observation started on 29 May 2024 at
21:57 (UT) to 30 May 2024 at 00:23 (UT), about 20.2 hours from the trigger.
We obtained multiple 180-sec exposures in Ic and Clear filters. We clearly
detected the optical afterglow at:
R.A. (J2000): 22:21:25.97
Dec. (J2000): +51:33:42.6
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).
The following observations were calculated using Atlas catalogue as a
reference:
