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 GRB220115.72 (trigger No 663960124,19h 36m 21.60s , +17d 50m 24.0s, R=2.15) errorbox  49180 sec after notice time and 49207 sec after trigger time at 2022-01-16 07:02:06 UT, with upper limit up to  16.3 mag. Observations started at twilight.  The observations began at zenith distance = 78 deg. The sun  altitude  is -11.8 deg. 

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