The Fermi GBM team reports the detection of a likely LONG GRB
At 21:43:07 UT on 29 Mar 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240329A (trigger 733441392.528372 / 240329905).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 259.7, Dec = -4.8 (J2000 degrees, equivalent to J2000 17h 18m, -4d 47'), with a statistical uncertainty of 3.8 degrees.
The angle from the Fermi LAT boresight is 97.0 degrees.
