MASTER-OAFA robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB201226.55 (trigger No 630681391,11h 32m 19.20s , -05d 58m 12.0s, R=3.79) errorbox  67592 sec after notice time and 67646 sec after trigger time at 2020-12-27 08:03:53 UT, with upper limit up to  18.8 mag. Observations started at twilight.  The observations began at zenith distance = 33 deg. The sun  altitude  is -16.3 deg. 

The galactic latitude b = 52 deg., longitude l = 271 deg.
