Levan (Radboud U.) report on behalf of a larger collaboration: We observed the field of GRB 200216B (Fermi GBM team GCN 27101; D���Avanzo et al. GCN 27102) with the 2.5 m Nordic Optical Telescope equipped with AlFOSC. Observations consisted of 5x200s imaging in z-band, with mean epoch 17 Feb 2020 00:11:22 UT (10.647 hr after the burst). We do not detect any source within the refined XRT error box (Goad et al. GCN 27106) down to a 3-sigma limit of z > 23.3 mag.
