Sergienko (Blagoveschensk Educational State University) 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: https://master.sai.msu.ru/site/master2/observ.php?id=1396328 We obtain a following upper limits.
