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 201108A ( Fermi GBM team, GCN 28866) errorbox  359 sec after notice time and 389 sec after trigger time at 2020-11-08 15:34:52 UT, with upper limit up to  16.7 mag. Observations started at twilight.  The observations began at zenith distance = 17 deg. The sun  altitude  is -13.0 deg. 

The galactic latitude b = 11 deg., longitude l = 68 deg.


Real time updated cover map and OT discovered available here:
