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 GRB 200929A ( Fermi GBM team, GCN 28525) errorbox  45480 sec after notice time and 45547 sec after trigger time at 2020-09-29 17:32:19 UT, with upper limit up to  18.4 mag. Observations started at twilight.  The observations began at zenith distance = 62 deg. The sun  altitude  is -11.9 deg. 

The galactic latitude b = 24 deg., longitude l = 326 deg.
