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

At 13:58:24 UT on 28 Mar 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230328A (trigger 701704709.245818 / 230328582).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 196.8, Dec = 1.1 (J2000 degrees, equivalent to J2000 13h 07m, 1d 06'), with a statistical uncertainty of 8.4 degrees.

The angle from the Fermi LAT boresight is 47.0 degrees.
