MASTER-OAFA robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB200617.68 (trigger No 614103490,08h 32m 45.60s , -64d 24m 36.0s, R=51.1) errorbox  26271 sec after notice time and 26298 sec after trigger time at 2020-06-17 23:36:24 UT, with upper limit up to  18.1 mag. The observations began at zenith distance = 56 deg. The sun  altitude  is -24.2 deg. 

The galactic latitude b = -14 deg., longitude l = 279 deg.
