Mainella (INAF-TNG), \non behalf of the CIBO collaboration report:\n\nWe observed the field of GRB 221009A (Dichiara et al., GCN 32632; Kennea & Williams, GCN 32635; Veres et al., \nGCN 32636; Bissaldi et al., GCN 32637; Svinkin et al., GCN 32641; Ursi et al., GCN Circ. 32650) with the Italian 3.6m \nTNG telescope equipped with the near-infrared camera NICS. A series of images were obtained with the J, H and K filters \non 2022-01-16 at a mid time of about 7.3 days after the GBM trigger time. \n\nThe NIR afterglow (Brivio et al., GCN Circ. 32652) is clearly detected in all bands. From preliminary photometry we derive \nthe following magnitude:\n\nH = 16.45 +/- 0.04\n\n(Vega; calibrated against the 2MASS catalogue).\n\n\nWe acknowledge the TNG visiting astronomers B. Lakeland and B. Nicholson for their support.",
