Following the detection of GRB 240529A by Swift (Eyles-Ferris et al. GCNC 36556), the BOOTES-6/DPRT 0.6m robotic telescope at Boyden Observatory in Maselspoort (South Africa) observed the GRB location starting on May. 29, 03:05 UT (~ 7 min after trigger). A series of images in clear filter were gathered and the optical afterglow was detected within the enhanced Swift/XRT position (Osborne et al. GCNC 36557) for which we measure a preliminary magnitude of 15.2 +- 0.1 on the first co-added 10 s x 4 image, which is consistent with the detections of GOTO (Kumar et al. GCNC 36559), NOT (Fu et al. GCNC 36561) and UVOT (Shilling et al. GCNC 36562). Further imaging is ongoing.

We thank the staff at Boyden Observatory for their excellent support.
