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) was pointed to the Swift GRB 201031A ( S. Laha et al., GCN 28814) errorbox 34924 sec after notice time and 35035 sec after trigger time at 2020-11-01 00:03:50 UT, with upper limit up to 16.6 mag. Observations started at twilight. The observations began at zenith distance = 76 deg. The sun altitude is -13.9 deg.
The galactic latitude b = 20 deg., longitude l = 11 deg.
Real time updated cover map and OT discovered available here:
