MASTER-IAC robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB 201103A ( Fermi GBM team, GCN 28820) errorbox  284 sec after notice time and 343 sec after trigger time at 2020-11-03 06:18:53 UT, with upper limit up to  16.7 mag. Observations started at twilight.  The observations began at zenith distance = 73 deg. The sun  altitude  is -13.0 deg. 

The galactic latitude b = 36 deg., longitude l = 103 deg.
