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 GRB220112.83 (trigger No 663710289,19h 19m 33.60s , +28d 49m 48.0s, R=2.43) errorbox  2822 sec after notice time and 2849 sec after trigger time at 2022-01-12 20:45:33 UT, with upper limit up to  16.0 mag. The observations began at zenith distance = 73 deg. The sun  altitude  is -24.9 deg. 

The galactic latitude b =  7 deg., longitude l = 62 deg.
