MASTER-Tavrida robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB 200403A ( Fermi GBM team, GCN 27482) errorbox  36 sec after notice time and 64 sec after trigger time at 2020-04-03 21:31:20 UT, with upper limit up to  18.5 mag. The observations began at zenith distance = 51 deg. The sun  altitude  is -40.2 deg. 

MASTER-Kislovodsk robotic telescope  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB 200403A errorbox  5527 sec after notice time and 5555 sec after trigger time at 2020-04-03 23:02:52 UT, with upper limit up to  18.9 mag. The observations began at zenith distance = 62 deg. The sun  altitude  is -35.4 deg. 

The galactic latitude b = 21 deg., longitude l = 142 deg.
