MASTER-Amur robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB200529.31 (trigger No 612429771,23h 26m 40.08s , +53d 30m 00.0s, R=32.05) errorbox  19945 sec after notice time and 19970 sec after trigger time at 2020-05-29 12:55:37 UT, with upper limit up to  14.8 mag. Observations started at twilight.  The observations began at zenith distance = 65 deg. The sun  altitude  is -10.7 deg. 

The galactic latitude b = -7 deg., longitude l = 111 deg.
