Following the detection of GRB 240529A by Swift (Eyles-Ferris et al. GCNC 36556), we triggered the 1.5m telescope of the Observatiorio Sierra Nevada (OSN) near Granada, Spain. Observations in the RI bands began on Jun. 1 at 01:06 UT (~ 2.9 days post burst). The afterglow is clearly detected with 19.4+-0.1 mag in the I-band image (exposure 300 s) within the enhanced XRT/Swift position (Osborne et al. GCNC 36557). Our result is consistent with previous reports from GOTO (Kumar et al. GCNC 36559), NOT (Fu et al. GCNC 36561), UVOT (Shilling et al. GCNC 36562), BOOTES (Perez-Garcia et al., GCNC 36563), Skynet (Dutton et al., GCNC 36568), WINTER (Mo et al., GCNC 36569), AKO (Odeh et al. GCNC 36573), GTC (de Ugarte Postigo et al., GCNC 36574), T193/MISTRAL (Adami et al., GCNC 36575), GROWTH (Mohan et al., GCNC 36576), Konkoly (Vinko et al., GCNC 36577), MAAO (Gu et al., GCNC 36579), SAO (Moskvitin et al., GCNC 36582, GCNC 36594), Mondy (Pankov et al., GCNC 36585) and DFOT (Ror et al., GCNC 36589). Further imaging is ongoing.
We thank the staff at OSN for their excellent support.
