TITLE: GCN CIRCULAR
NUMBER: 33171
SUBJECT: GRB 230116A: Fermi GBM Final Real-time Localization
DATE: 23/01/16 05:05:00 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 04:54:34 UT on 16 Jan 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230116A (trigger 695537679.288856 / 230116205).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 81.3, Dec = -49.7 (J2000 degrees, equivalent to J2000 05h 25m, -49d 42'), with a statistical uncertainty of 2.1 degrees.
The angle from the Fermi LAT boresight is 70.0 degrees.
