MASTER-Kislovodsk robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB 211216B ( Fermi GBM team, GCN 31244) errorbox  5497 sec after notice time and 5506 sec after trigger time at 2021-12-16 14:52:53 UT, with upper limit up to  16.8 mag. Observations started at twilight.  The observations began at zenith distance = 62 deg. The sun  altitude  is -13.3 deg. 

The galactic latitude b = 23 deg., longitude l = 156 deg.
