The Fermi GBM team reports the detection of a likely LONG GRB
At 05:40:08 UT on 10 Mar 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240310A (trigger 731742013.593492 / 240310236).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 312.5, Dec = -4.9 (J2000 degrees, equivalent to J2000 20h 49m, -4d 54'), with a statistical uncertainty of 10.5 degrees.
The angle from the Fermi LAT boresight is 87.0 degrees.
