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.
