TITLE: GCN CIRCULAR
NUMBER: 35404
SUBJECT: GRB 231219A: Fermi GBM Final Real-time Localization
DATE: 23/12/19 17:22:54 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 17:12:22 UT on 19 Dec 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231219A (trigger 724698747.778088 / 231219717).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 231.6, Dec = 58.0 (J2000 degrees, equivalent to J2000 15h 26m, 58d 00'), with a statistical uncertainty of 14.2 degrees.
The angle from the Fermi LAT boresight is 21.0 degrees.
