MASTER-SAAO robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB 200705A ( Fermi GBM team, GCN 28062) errorbox  33087 sec after notice time and 33114 sec after trigger time at 2020-07-06 01:21:47 UT, with upper limit up to  18.4 mag. The observations began at zenith distance = 67 deg. The sun  altitude  is -53.9 deg. 

The galactic latitude b = -71 deg., longitude l = 241 deg.


Real time updated cover map and OT discovered available here:
