The Fermi GBM team reports the detection of a likely LONG GRB
At 19:09:10 UT on 28 Mar 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240328B (trigger 733345755.665982 / 240328798).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 223.4, Dec = -20.1 (J2000 degrees, equivalent to J2000 14h 53m, -20d 06'), with a statistical uncertainty of 11.6 degrees.
The angle from the Fermi LAT boresight is 78.0 degrees.
