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 200313A ( Fermi GBM team, GCN 27374) errorbox  41 sec after notice time and 71 sec after trigger time at 2020-03-13 01:42:47 UT, with upper limit up to  17.4 mag. The observations began at zenith distance = 72 deg. The sun  altitude  is -35.1 deg. 

The galactic latitude b = -12 deg., longitude l = 182 deg.


Real time updated cover map and OT discovered available here:
