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) was pointed to the Swift GRB201216.96 (trigger No 1013243,01h 05m 25.92s , +16d 32m 13.2s, R=0.05) errorbox  39 sec after notice time and 68 sec after trigger time at 2020-12-16 23:08:40 UT, with upper limit up to  17.6 mag. The observations began at zenith distance = 79 deg. The sun  altitude  is -62.3 deg. 

The galactic latitude b = -46 deg., longitude l = 129 deg.


Real time updated cover map and OT discovered available here:
