TITLE: GCN CIRCULAR NUMBER: 33036 SUBJECT: GRB 221210A: Fermi GBM Final Real-time Localization DATE: 22/12/10 02:46:04 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely SHORT GRB At 02:35:38 UT on 10 Dec 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 221210A (trigger 692332543.436908 / 221210108). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 259.0, Dec = -12.9 (J2000 degrees, equivalent to J2000 17h 15m, -12d 54'), with a statistical uncertainty of 8.1 degrees. The angle from the Fermi LAT boresight is 50.0 degrees.
