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 GRB220112.36 (trigger No 663669570,19h 19m 12.00s , +18d 33m 00.0s, R=2.08) errorbox  898 sec after notice time and 926 sec after trigger time at 2022-01-12 08:54:51 UT, with upper limit up to  12.4 mag. Observations started at twilight.  The observations began at zenith distance = 72 deg. The sun  altitude  is -9.7 deg. 

The galactic latitude b =  2 deg., longitude l = 53 deg.


Real time updated cover map and OT discovered available here:
