We report detection and photometry of the optical afterglow of GRB 240529A (Eyles-Ferris et al. GCN 36556; Osborne et al. GCN 36557; Dichiara et al. GCN 36564; Markwardt et al. GCN 36566) taken with the RC80 robotic telescope at Piszkesteto Station of Konkoly Observatory, Hungary. The observations started on 2024-05-29 22:40:46.49 UT. 5 sets of 300 sec frames were collected through Sloan g', r'- and i' bands.
The optical afterglow (Kumar et al. GCN 36559; Joshi et al. GCN 36560; 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. GCN 36573; de Ugarte Postigo et al. GCN 36574; Adami et al. GCN 36575; Mohan et al. GCN 36576) was detected on the stacked frames with the following magnitudes, calibrated via nearby PS1 stars:
Date UT-middle t-T0(days) Exp(s) g'(AB) r'(AB) i'(AB) 2024-05-29 23:11:35.78 0.842 5x300 20.28 (0.21) 19.08 (0.09) 18.62 (0.09)
The magnitudes above are not corrected for galactic extinction.
