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) was pointed to the Swift GRB200205.81 (trigger No 954519,07h 11m 12.72s , -56d 28m 51.6s, R=0.05) errorbox  21 sec after notice time and 300 sec after trigger time at 2020-02-05 19:26:44 UT, with upper limit up to  18.0 mag. The observations began at zenith distance = 28 deg. The sun  altitude  is -21.2 deg. 

The galactic latitude b = -20 deg., longitude l = 267 deg.
