The Fermi GBM team reports the detection of a likely LONG GRB
At 02:02:55 UT on 4 Sep 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200904A (trigger 620877780.28243 / 200904085).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 15.8, Dec = -16.0 (J2000 degrees, equivalent to J2000 01h 03m, -16d 00'), with a statistical uncertainty of 11.6 degrees.
The angle from the Fermi LAT boresight is 102.0 degrees.
