MASTER-IAC robotic telescope  (Global MASTER-Net:, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB220114.87 (trigger No 663886592,21h 02m 48.00s , +29d 52m 00.1s, R=30.65) errorbox  1 days 31652 sec after notice time and 1 days 33198 sec after trigger time at 2022-01-16 06:09:45 UT, with upper limit up to  16.6 mag. The observations began at zenith distance = 78 deg. The sun  altitude  is -23.0 deg. 

The galactic latitude b = -11 deg., longitude l = 75 deg.

Real time updated cover map and OT discovered available here:

We obtain a following upper limits.
