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 GRB200410.41 (trigger No 608204639,19h 45m 33.60s , +15d 06m 00.0s, R=3.52) errorbox  25576 sec after notice time and 25603 sec after trigger time at 2020-04-10 16:50:37 UT, with upper limit up to  16.5 mag. The observations began at zenith distance = 68 deg. The sun  altitude  is -29.3 deg. 

MASTER-Tunka robotic telescope  located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB200410.41 errorbox  31716 sec after notice time and 31743 sec after trigger time at 2020-04-10 18:32:57 UT, with upper limit up to  17.3 mag. The observations began at zenith distance = 65 deg. The sun  altitude  is -28.0 deg. 

The galactic latitude b = -5 deg., longitude l = 53 deg.
