MASTER-OAFA robotic telescope  (Global MASTER-Net:, 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 GRB191211.25 (trigger No 597737032,10h 52m 48.00s , -70d 15m 00.0s, R=6.75) errorbox  2051 sec after notice time and 2096 sec after trigger time at 2019-12-11 06:38:44 UT, with upper limit up to  17.3 mag. The observations began at zenith distance = 45 deg. The sun  altitude  is -27.6 deg. 

The galactic latitude b = -10 deg., longitude l = 293 deg.

Real time updated cover map and OT discovered available here:

We obtain a following upper limits.
