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 200616A ( Fermi GBM team, GCN 27959) errorbox  304 sec after notice time and 338 sec after trigger time at 2020-06-16 01:14:54 UT, with upper limit up to  19.6 mag. The observations began at zenith distance = 72 deg. The sun  altitude  is -54.7 deg. 

MASTER-OAFA robotic telescope  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB 200616A errorbox  601 sec after notice time and 635 sec after trigger time at 2020-06-16 01:19:51 UT, with upper limit up to  17.5 mag. The observations began at zenith distance = 65 deg. The sun  altitude  is -46.2 deg. 

The galactic latitude b = -21 deg., longitude l = 293 deg.
