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) was pointed to the Integral GRB200914.53 (trigger No 8711,16h 57m 59.03s , -36d 18m 59.5s, R=0.0495) errorbox  38109 sec after notice time and 38209 sec after trigger time at 2020-09-14 23:25:20 UT, with upper limit up to  18.1 mag. Observations started at twilight.  The observations began at zenith distance = 20 deg. The sun  altitude  is -13.4 deg. 

The galactic latitude b =  3 deg., longitude l = 349 deg.
