The Fermi GBM team reports the detection of a likely LONG GRB
"At 06:25:22.05 UT on 08 March 2024, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 240308A (trigger 731571927 / 240308268).
The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 77.89, Dec = 50.92 (J2000 degrees, equivalent to J2000 05h 11m, 50d 55'),
with a statistical uncertainty of Error Radius = 4.56 degrees.
The angle from the Fermi LAT boresight is 25 degrees.
