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:
