We observed the field of the GRB240529A detected by the Swift (Eyles-Ferris et al., GCNC 36556), AstroSat (Joshi et al., GCNC 36560), Insight-HXMT (Tan et al., GCNC 36578), IPN (Kozyrev et al., GCNC 36583) and Konus-Wind (Svinkin et al., GCNC 36584) with the Italian 3.6m TNG telescope equipped with the near-infrared camera NICS to follow up its afterglow. A series of images were obtained with the J filter starting on 2024-06-06 04:42:44 UT (i.e. 8.1 days post T0). The afterglow (Kumar et al. GCNC 36559, Fu et al. GCNC 36561, Shilling et al. GCNC 36562, Perez-Garcia et al., GCNC 36563, Dutton et al., GCNC 36568, Mo et al., GCNC 36569, Odeh et al.
