TITLE: GCN CIRCULAR NUMBER: 33225 SUBJECT: GRB 230126A: Fermi GBM Final Real-time Localization DATE: 23/01/26 18:31:09 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 18:20:44 UT on 26 Jan 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230126A (trigger 696450049.448062 / 230126764). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 96.9, Dec = -27.0 (J2000 degrees, equivalent to J2000 06h 27m, -27d 00'), with a statistical uncertainty of 11.8 degrees. The angle from the Fermi LAT boresight is 91.0 degrees.
