MASTER-Tavrida robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB200829.58 (trigger No 620402299,18h 18m 24.00s , +78d 34m 58.8s, R=11.17) errorbox  12410 sec after notice time and 12420 sec after trigger time at 2020-08-29 17:25:15 UT, with upper limit up to  18.9 mag. Observations started at twilight.  The observations began at zenith distance = 34 deg. The sun  altitude  is -11.2 deg. 

The galactic latitude b = 28 deg., longitude l = 110 deg.
