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 200601A ( Fermi GBM team, GCN 27876) errorbox  8734 sec after notice time and 8763 sec after trigger time at 2020-06-01 04:45:53 UT, with upper limit up to  17.6 mag. Observations started at twilight.  The observations began at zenith distance = 72 deg. The sun  altitude  is -16.1 deg. 

The galactic latitude b = -26 deg., longitude l = 122 deg.
