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 200802A ( Fermi GBM team, GCN 28190) errorbox  23912 sec after notice time and 23939 sec after trigger time at 2020-08-02 18:25:46 UT, with upper limit up to  18.4 mag. Observations started at twilight.  The observations began at zenith distance = 42 deg. The sun  altitude  is -12.9 deg. 

The galactic latitude b =  0 deg., longitude l = 101 deg.


Real time updated cover map and OT discovered available here:
