The Fermi GBM team reports the detection of a likely LONG GRB
At 17:29:47 UT on 20 Mar 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240320A (trigger 732648592.559252 / 240320729).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 150.8, Dec = 63.4 (J2000 degrees, equivalent to J2000 10h 03m, 63d 23'), with a statistical uncertainty of 14.5 degrees.
The angle from the Fermi LAT boresight is 55.0 degrees.
