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

At 14:55:06 UT on 28 Aug 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240828A (trigger 746549711.829992 / 240828622).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 219.1, Dec = 35.8 (J2000 degrees, equivalent to J2000 14h 36m, 35d 47'), with a statistical uncertainty of 1.0 degrees.

The angle from the Fermi LAT boresight is 93.0 degrees.
