Fermi GBM Team at MSFC/Fermi-GBM <>
The Fermi GBM team reports the detection of a likely LONG GRB

At 11:07:29 UT on 15 Mar 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240315A (trigger 732193654.441586 / 240315464).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 199.5, Dec = 21.9 (J2000 degrees, equivalent to J2000 13h 18m, 21d 53'), with a statistical uncertainty of 14.1 degrees.

The angle from the Fermi LAT boresight is 77.0 degrees.
