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 GRB200604.78 (trigger No 612988790,00h 32m 48.00s , +18d 31m 58.8s, R=27.48) errorbox  5015 sec after notice time and 5043 sec after trigger time at 2020-06-04 20:03:49 UT, with upper limit up to  16.3 mag. The observations began at zenith distance = 79 deg. The sun  altitude  is -22.8 deg. 

MASTER-Tavrida robotic telescope  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB200604.78 errorbox  13373 sec after notice time and 13401 sec after trigger time at 2020-06-04 22:23:07 UT, with upper limit up to  19.2 mag. The observations began at zenith distance = 71 deg. The sun  altitude  is -22.8 deg. 

MASTER-SAAO robotic telescope  located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB200604.78 errorbox  22793 sec after notice time and 22821 sec after trigger time at 2020-06-05 01:00:07 UT, with upper limit up to  17.3 mag. The observations began at zenith distance = 73 deg. The sun  altitude  is -57.1 deg. 

The galactic latitude b = -44 deg., longitude l = 118 deg.
