MASTER-IAC robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB220106.11 (trigger No 663129379,19h 30m 43.92s , +18d 28m 01.2s, R=10.3) errorbox  15346 sec after notice time and 15375 sec after trigger time at 2022-01-06 06:52:29 UT, with upper limit up to  16.0 mag. Observations started at twilight.  The observations began at zenith distance = 78 deg. The sun  altitude  is -13.7 deg. 

The galactic latitude b = -0 deg., longitude l = 54 deg.
