The Fermi GBM team reports the detection of a likely LONG GRB
At 19:28:39 UT on 16 Sep 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200916A (trigger 621977324.956902 / 200916812).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 41.5, Dec = -4.7 (J2000 degrees, equivalent to J2000 02h 46m, -4d 42'), with a statistical uncertainty of 8.0 degrees.
The angle from the Fermi LAT boresight is 96.0 degrees.

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 200916A ( Fermi GBM team, GCN 28431) errorbox 40 sec after notice time and 52 sec after trigger time at 2020-09-16 19:29:32 UT, with upper limit up to 17.7 mag. The observations began at zenith distance = 82 deg. The sun altitude is -37.6 deg.
The galactic latitude b = -54 deg., longitude l = 179 deg.
