The Fermi GBM team reports the detection of a likely LONG GRB

At 18:07:25 UT on 15 Nov 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241115B (trigger 753386850.967696 / 241115755).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 31.8, Dec = 45.0 (J2000 degrees, equivalent to J2000 02h 07m, 45d 00'), with a statistical uncertainty of 9.2 degrees.

The angle from the Fermi LAT boresight is 97.0 degrees.
