TITLE: GCN CIRCULAR
NUMBER: 35129
SUBJECT: GRB 231120A: Fermi GBM Final Real-time Localization
DATE: 23/11/20 00:32:39 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 00:23:08 UT on 20 Nov 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231120A (trigger 722132593.748426 / 231120016).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 50.7, Dec = 1.4 (J2000 degrees, equivalent to J2000 03h 22m, 1d 23'), with a statistical uncertainty of 18.2 degrees.
The angle from the Fermi LAT boresight is 73.0 degrees.
