The Fermi GBM team reports the detection of a likely LONG GRB
At 02:51:24 UT on 14 Mar 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230314A (trigger 700455089.129136 / 230314119).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 236.4, Dec = 74.8 (J2000 degrees, equivalent to J2000 15h 45m, 74d 47'), with a statistical uncertainty of 4.6 degrees.
The angle from the Fermi LAT boresight is 40.0 degrees.
