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 GRB200203.86 (trigger No 602455182,17h 32m 48.00s , -45d 04m 48.0s, R=8.92) errorbox  7916 sec after trigger time at 2020-02-03 22:51:34 UT, with upper limit up to  17.1 mag. The observations began at zenith distance = 79 deg. The sun  altitude  is -41.5 deg. 

The galactic latitude b = -7 deg., longitude l = 345 deg.
