The Fermi GBM team reports the detection of a likely SHORT GRB
"At 09:18:40.39 UT on 14 November 2023, the Fermi Gamma-ray Burst Monitor
(GBM)
triggered and located GRB 231114A (trigger 721646325/231114388).
The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 150.00, Dec = -36.55 (J2000 degrees, equivalent to J2000 10h 0m,
-36d 32'),
with a statistical uncertainty of 11.38 degrees.
The angle from the Fermi LAT boresight is 77 degrees.

C.C. Cheung, M. Kerr, J. E. Grove, R. Woolf (NRL), A. Goldstein (USRA), C.A. Wilson-Hodge (MSFC), and M.S. Briggs (UAH) report:
The Glowbug gamma-ray telescope [1,2], operating on the International Space Station, reports the detection of GRB 231114A, which was also detected by Fermi/GBM (GCN 35025).
Using an adaptive window with a resolution of 32-ms, the burst onset is determined to be 2023-11-14 09:18:39.280 with a duration of 0.256 s and a total significance of about 11.6 sigma. The light curve comprises a single peak.
Using a standard power-law function with an exponential high-energy cutoff [3] to model the emission over this duration results in a photon index dN/dE~E^x of x=-0.1 and a cutoff energy ("Epeak") of 421 keV. The modeled 10-10000 keV fluence is 1.5e-07 erg/cm^2.
The analysis results presented here are preliminary and use a response function that lacks a detailed characterization of the surrounding passive structure of the ISS.
Glowbug is a NASA-funded technology demonstrator for sensitive, low-cost gamma-ray transient telescopes developed, built, and operated by the U.S. Naval Research Laboratory (NRL) with support from the University of Alabama in Huntsville, USRA, and NASA MSFC. It was launched on 2023 March 15 aboard the Department of Defense Space Test Program’s STP-H9 to the ISS. The detector comprises 12 large-area (15 cm x 15 cm) CsI:Tl panels covering the surface of a half cube, and two hexagonal (5-cm diameter, 10-cm length) CLLB scintillators, giving it a large field of view (instantaneous FoV ~2/3 sky) over a wide energy band of 50 keV to >2 MeV.
