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

"At 03:52:49.30 UT on 05 March 2024, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 240305B (trigger 731303574 / 240305162).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 10.37, Dec = -21.98 (J2000 degrees, equivalent to J2000 00h 41m, -21d 59'),
with a statistical uncertainty of 3.05 degrees.

The angle from the Fermi LAT boresight is 35 degrees.
