The Fermi GBM team reports the detection of a likely LONG GRB
"At 00:26:04 UT on 30 March 2023, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 230330B (trigger 701828769/230330018).
The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 65.05, Dec = -35.22 (J2000 degrees, equivalent to J2000 4h 20m, -35d 13'),
with a statistical uncertainty of 8.61 degrees.
The angle from the Fermi LAT boresight is 32 degrees.
