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 GRB200706.63 (trigger No 615741133,08h 27m 00.00s , -06d 09m 00.0s, R=26.9) errorbox  27043 sec after notice time and 27070 sec after trigger time at 2020-07-06 22:43:18 UT, with upper limit up to  17.8 mag. Observations started at twilight.  The observations began at zenith distance = 70 deg. The sun  altitude  is -12.1 deg. 

The galactic latitude b = 18 deg., longitude l = 230 deg.

Real time updated cover map and OT discovered available here:

We obtain a following upper limits.
