MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB 200604A ( Fermi GBM team, GCN 27887) errorbox 405 sec after notice time and 432 sec after trigger time at 2020-06-04 20:07:17 UT, with upper limit up to 18.5 mag. The observations began at zenith distance = 45 deg. The sun altitude is -55.5 deg.
MASTER-Kislovodsk robotic telescope located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB 200604A errorbox 2698 sec after notice time and 2725 sec after trigger time at 2020-06-04 20:45:30 UT, with upper limit up to 17.0 mag. The observations began at zenith distance = 77 deg. The sun altitude is -24.2 deg.
MASTER-IAC robotic telescope located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB 200604A errorbox 4925 sec after notice time and 4951 sec after trigger time at 2020-06-04 21:22:36 UT, with upper limit up to 17.8 mag. Observations started at twilight. The observations began at zenith distance = 43 deg. The sun altitude is -17.0 deg.
The galactic latitude b = 56 deg., longitude l = 279 deg.
