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 GRB 201207A ( Fermi GBM team, GCN 28996) errorbox  3980 sec after notice time and 4062 sec after trigger time at 2020-12-08 00:34:37 UT, with upper limit up to  16.0 mag. Observations started at twilight.  The observations began at zenith distance = 76 deg. The sun  altitude  is -12.7 deg. 

The galactic latitude b = -8 deg., longitude l = 266 deg.


Real time updated cover map and OT discovered available here:
