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 200716A ( Fermi GBM team, GCN 28109) errorbox  55482 sec after notice time and 55509 sec after trigger time at 2020-07-16 16:51:47 UT, with upper limit up to  19.0 mag. Observations started at twilight.  The observations began at zenith distance = 63 deg. The sun  altitude  is -12.5 deg. 

The galactic latitude b =  9 deg., longitude l = 252 deg.
