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 GRB200205.85 (trigger No 602626648,14h 52m 50.40s , -42d 46m 48.0s, R=9.77) errorbox  16207 sec after trigger time at 2020-02-06 00:47:30 UT, with upper limit up to  13.2 mag. The observations began at zenith distance = 46 deg. The sun  altitude  is -34.8 deg. 

The galactic latitude b = 14 deg., longitude l = 326 deg.


Real time updated cover map and OT discovered available here:
