The Fermi GBM team reports the detection of a likely LONG GRB
At 11:46:46 UT on 2 Aug 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200802A (trigger 618061611.842764 / 200802491).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 329.8, Dec = 54.8 (J2000 degrees, equivalent to J2000 21h 59m, 54d 47'), with a statistical uncertainty of 2.1 degrees.
The angle from the Fermi LAT boresight is 99.0 degrees.
