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

At 12:59:59 UT on 28 Aug 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190828B (trigger 588690004.456526 / 190828542).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 246.6, Dec = 24.6 (J2000 degrees, equivalent to J2000 16h 26m, 24d 36'), with a statistical uncertainty of 1.0 degrees.

The angle from the Fermi LAT boresight is 17.0 degrees.
