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 200607B ( Fermi GBM team, GCN 27902) errorbox 24 sec after notice time and 53 sec after trigger time at 2020-06-07 22:07:24 UT, with upper limit up to 17.8 mag. The observations began at zenith distance = 62 deg. The sun altitude is -78.6 deg.
The galactic latitude b = -33 deg., longitude l = 301 deg.
Real time updated cover map and OT discovered available here:
