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 200702A ( Fermi GBM team, GCN 28056) errorbox  2633 sec after notice time and 2660 sec after trigger time at 2020-07-02 22:08:39 UT, with upper limit up to  17.4 mag. The observations began at zenith distance = 56 deg. The sun  altitude  is -78.2 deg. 

MASTER-OAFA robotic telescope  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB 200702A errorbox  4891 sec after notice time and 4918 sec after trigger time at 2020-07-02 22:46:17 UT, with upper limit up to  16.1 mag. Observations started at twilight.  The observations began at zenith distance = 57 deg. The sun  altitude  is -13.1 deg. 

The galactic latitude b = -20 deg., longitude l = 324 deg.
