GRB 231205A: Fermi GBM Final Real-time Localization
2023-12-05T02:35:45Z (5 months ago)
Fermi GBM Team at MSFC/Fermi-GBM <>
The Fermi GBM team reports the detection of a likely SHORT GRB

At 02:25:11 UT on 5 Dec 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231205A (trigger 723435916.407408 / 231205101).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 206.1, Dec = 22.8 (J2000 degrees, equivalent to J2000 13h 44m, 22d 48'), with a statistical uncertainty of 3.1 degrees.

The angle from the Fermi LAT boresight is 79.0 degrees.
