Terwel (NOT) report on behalf of a large collaboration:\n\nWe observed the field of GRB 240529A detected by Swift (Eyles-Ferris et al., GCN 36556) using the 2.56-m Nordic Optical Telescope (NOT) equipped with the ALFOSC camera, and obtained 3 x 100 s frames in the Sloan r-band and 3 x 100 s frames in z-band, starting at 04:51:50.7 UT on 2024-05-29, i.e., 1.89 hr after the BAT trigger.\n\nThe optical afterglow (Eyles-Ferris et al., GCN 36556; Kumar et al. GCN 36559) of the burst is clearly detected in our stacked images. Preliminary photometry results are as follows:\n\n   Tmid (UT)        Tmid-T0(hr)    Mag    MagErr  Filter\n2024-05-29T04:54:47    1.94       16.48    0.05      r\n2024-05-29T05:01:30    2.05       15.40    0.05      z\n\ncalibrated with nearby PanSTARRS stars.",
