The Fermi GBM team reports the detection of a likely LONG GRB

At 13:11:53 UT on 6 Sep 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200906A (trigger 621090718.377264 / 200906550).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 270.0, Dec = 68.6 (J2000 degrees, equivalent to J2000 18h 00m, 68d 35'), with a statistical uncertainty of 4.1 degrees.

The angle from the Fermi LAT boresight is 83.0 degrees.
