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 GRB 200605A ( Fermi GBM team, GCN 27892) errorbox  83 sec after notice time and 111 sec after trigger time at 2020-06-05 18:19:33 UT, with upper limit up to  18.0 mag. Observations started at twilight.  The observations began at zenith distance = 74 deg. The sun  altitude  is -13.6 deg. 

MASTER-Tavrida robotic telescope  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB 200605A errorbox  1260 sec after notice time and 1288 sec after trigger time at 2020-06-05 18:39:10 UT, with upper limit up to  16.1 mag. Observations started at twilight.  The observations began at zenith distance = 70 deg. The sun  altitude  is -11.4 deg. 

The galactic latitude b = 17 deg., longitude l = 161 deg.
