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 201229B ( Fermi GBM team, GCN 29194) errorbox  15696 sec after notice time and 15741 sec after trigger time at 2020-12-29 19:42:34 UT, with upper limit up to  17.8 mag. The observations began at zenith distance = 59 deg. The sun  altitude  is -20.2 deg. 

The galactic latitude b = -56 deg., longitude l = 338 deg.
