TITLE: GCN CIRCULAR
NUMBER: 35344
SUBJECT: GRB 231215B: Fermi GBM Final Real-time Localization
DATE: 23/12/15 09:57:45 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 09:47:17 UT on 15 Dec 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231215B (trigger 724326442.811262 / 231215408).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 11.1, Dec = 61.2 (J2000 degrees, equivalent to J2000 00h 44m, 61d 12'), with a statistical uncertainty of 1.0 degrees.
The angle from the Fermi LAT boresight is 114.0 degrees.
