MASTER-Kislovodsk robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB200520.59 (trigger No 611676654,18h 53m 52.08s , +26d 52m 01.2s, R=34.83) errorbox  15061 sec after notice time and 15089 sec after trigger time at 2020-05-20 18:22:19 UT, with upper limit up to  17.4 mag. Observations started at twilight.  The observations began at zenith distance = 80 deg. The sun  altitude  is -16.3 deg. 

The galactic latitude b = 11 deg., longitude l = 58 deg.
