A. de Ugarte Postigo (IAA-CSIC, DARK/NBI), J. Martikainen (NOT and 
U. Helsinki), D. Perley (LJMU), K.E. Heintz (U. Iceland), D. Xu (NAOC),
A. 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.
