MASTER-Tunka robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB 200808A ( Fermi GBM team, GCN 28230) errorbox  15558 sec after notice time and 15585 sec after trigger time at 2020-08-08 15:35:43 UT, with upper limit up to  15.1 mag. The observations began at zenith distance = 48 deg. The sun  altitude  is -19.8 deg. 

The galactic latitude b =  2 deg., longitude l = 125 deg.


Real time updated cover map and OT discovered available here:
