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) was pointed to the Integral GRB201214.26 (trigger No 74429,11h 24m 00.12s , +33d 51m 11.8s, R=0.0541667) errorbox  1 sec after notice time and 28 sec after trigger time at 2020-12-14 06:19:23 UT, with upper limit up to  19.9 mag. The observations began at zenith distance =  9 deg. The sun  altitude  is -18.6 deg. 

The galactic latitude b = 71 deg., longitude l = 188 deg.
