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 GRB220112.24 (trigger No 663658976,19h 22m 00.00s , +19d 04m 01.2s, R=34.22) errorbox  3030 sec after notice time and 3057 sec after trigger time at 2022-01-12 06:33:48 UT, with upper limit up to  17.4 mag. The observations began at zenith distance = 78 deg. The sun  altitude  is -17.8 deg. 

The galactic latitude b =  2 deg., longitude l = 54 deg.
