TITLE: GCN CIRCULAR
NUMBER: 33300
SUBJECT: GRB 230208A: Fermi GBM Final Real-time Localization
DATE: 23/02/08 09:20:32 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 09:10:08 UT on 8 Feb 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230208A (trigger 697540213.924094 / 230208382).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 81.0, Dec = 54.7 (J2000 degrees, equivalent to J2000 05h 24m, 54d 42'), with a statistical uncertainty of 26.7 degrees.
The angle from the Fermi LAT boresight is 62.0 degrees.
