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 GRB 201203A ( S. Dichiara et al., GCN 28985Not found
 
 
) errorbox  41763 sec after notice time and 41845 sec after trigger time at 2020-12-03 18:29:52 UT, with upper limit up to  17.6 mag. The observations began at zenith distance = 72 deg. The sun  altitude  is -46.7 deg. 

The galactic latitude b = -67 deg., longitude l = 217 deg.


Real time updated cover map and OT discovered available here:
