MASTER-Amur robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB 200407B ( Fermi GBM team, GCN 27503) errorbox  7492 sec after notice time and 7519 sec after trigger time at 2020-04-07 11:23:52 UT, with upper limit up to  16.3 mag. Observations started at twilight.  The observations began at zenith distance = 37 deg. The sun  altitude  is -11.7 deg. 

MASTER-Tunka robotic telescope  located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB 200407B errorbox  17824 sec after notice time and 17851 sec after trigger time at 2020-04-07 14:16:05 UT, with upper limit up to  16.3 mag. The observations began at zenith distance = 25 deg. The sun  altitude  is -21.1 deg. 

The galactic latitude b = 78 deg., longitude l = 168 deg.
