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 GRB200112.53 (trigger No 600525396,10h 00m 31.20s , +64d 24m 36.0s, R=2) errorbox  44 sec after notice time and 80 sec after trigger time at 2020-01-12 12:37:51 UT, with upper limit up to  16.5 mag. The observations began at zenith distance = 43 deg. The sun  altitude  is -44.7 deg. 

The galactic latitude b = 44 deg., longitude l = 147 deg.
