"At 23:13:45.38 UT on 30 November 2024, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 241130A (trigger 754701230/241130968).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 100.29, Dec = -26.38 (J2000 degrees, equivalent to
J2000 6h 41m, -26d 22'), with a statistical uncertainty of 1.00 degrees.
(radius, 1-sigma containment, statistical only; there is additionally a
systematic error which we have characterized as a mixture of two Gaussians,
one with a radius of 1.8 degrees (52% contribution) and one with a radius
of 4.1 degrees (47% contribution) [A. Goldstein et al. 2020, ApJ, 895, 1]).

The angle from the Fermi LAT boresight is 95 degrees.

The GBM light curve consists of a single emission episode 
with a duration (T90) of about 4.6 s (50-300 keV). 
The time-averaged spectrum from T0+0 to T0+4.544 s is 
best fit by a Band function  with Epeak = 320 +/- 30 keV, 
alpha = -0.92 +/- 0.04, and beta = -2.04 +/- 0.07.

The event fluence (10-1000 keV) in this time interval is
(1.09 +/- 0.02)E-05 erg/cm^2. The 1-sec peak photon flux measured
starting from T0+0.22 s in the 10-1000 keV band is 33.6 +/- 0.5 ph/s/cm^2.

The spectral analysis results presented above are preliminary;
final results will be published in the GBM GRB Catalog:
