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 GRB220115.30 (trigger No 663923149,18h 58m 57.60s , +22d 24m 36.0s, R=6.26) errorbox  83014 sec after notice time and 83040 sec after trigger time at 2022-01-16 06:09:45 UT, with upper limit up to  17.0 mag. The observations began at zenith distance = 78 deg. The sun  altitude  is -23.0 deg. 

The galactic latitude b =  8 deg., longitude l = 54 deg.
