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 201111A ( Fermi GBM team, GCN 28878) errorbox  49227 sec after notice time and 49238 sec after trigger time at 2020-11-11 21:26:24 UT, with upper limit up to  18.8 mag. The observations began at zenith distance = 56 deg. The sun  altitude  is -63.7 deg. 

The galactic latitude b = -26 deg., longitude l = 219 deg.


Real time updated cover map and OT discovered available here:
