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 GRB201127.15 (trigger No 628140709,09h 34m 43.20s , +42d 43m 48.0s, R=6.58) errorbox  7931 sec after notice time and 11608 sec after trigger time at 2020-11-27 06:45:13 UT, with upper limit up to  17.6 mag. The observations began at zenith distance = 78 deg. The sun  altitude  is -27.6 deg. 

The galactic latitude b = 48 deg., longitude l = 178 deg.
