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 GRB220115.34 (trigger No 663927396,22h 32m 36.00s , +31d 22m 58.8s, R=31.32) errorbox  41121 sec after notice time and 41126 sec after trigger time at 2022-01-15 19:41:57 UT, with upper limit up to  18.8 mag. Observations started at twilight.  The observations began at zenith distance = 24 deg. The sun  altitude  is -16.0 deg. 

The galactic latitude b = -23 deg., longitude l = 92 deg.
