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 201007A ( Fermi GBM team, GCN 28569) errorbox  22 sec after notice time and 92 sec after trigger time at 2020-10-07 02:58:10 UT, with upper limit up to  18.2 mag. The observations began at zenith distance = 63 deg. The sun  altitude  is -48.3 deg. 

The galactic latitude b = -12 deg., longitude l = 42 deg.


Real time updated cover map and OT discovered available here:
