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

At 05:48:03 UT on 30 Oct 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241030A (trigger 751960088.32731 / 241030242).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 331.0, Dec = 77.8 (J2000 degrees, equivalent to J2000 22h 03m, 77d 47'), with a statistical uncertainty of 5.1 degrees.

The angle from the Fermi LAT boresight is 19.0 degrees.
