MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB 200919C ( Fermi GBM team, GCN 28461) errorbox 92 sec after notice time and 120 sec after trigger time at 2020-09-19 23:10:23 UT, with upper limit up to 17.6 mag. Observations started at twilight. The observations began at zenith distance = 9 deg. The sun altitude is -9.6 deg.
MASTER-SAAO robotic telescope located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB 200919C errorbox 119 sec after notice time and 147 sec after trigger time at 2020-09-19 23:10:50 UT, with upper limit up to 14.2 mag. The observations began at zenith distance = 80 deg. The sun altitude is -57.8 deg.
The galactic latitude b = -3 deg., longitude l = 8 deg.
