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 200311A ( Fermi GBM team, GCN 27363) errorbox  30385 sec after trigger time at 2020-03-11 23:42:38 UT, with upper limit up to  17.9 mag. Observations started at twilight.  The observations began at zenith distance = 76 deg. The sun  altitude  is -10.6 deg. 

MASTER-IAC robotic telescope  located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB 200311A errorbox  39226 sec after trigger time at 2020-03-12 02:09:59 UT, with upper limit up to  16.7 mag. The observations began at zenith distance = 79 deg. The sun  altitude  is -61.8 deg. 

The galactic latitude b = 12 deg., longitude l = 311 deg.
