MASTER-Tavrida robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB 201214B ( Fermi GBM team, GCN 29039) errorbox  27106 sec after notice time and 27134 sec after trigger time at 2020-12-14 23:40:01 UT, with upper limit up to  19.1 mag. The observations began at zenith distance = 78 deg. The sun  altitude  is -57.5 deg. 

The galactic latitude b = 70 deg., longitude l = 346 deg.
