TITLE: GCN CIRCULAR NUMBER: 35464 SUBJECT: GRB 240102B: Fermi GBM Final Real-time Localization DATE: 24/01/02 22:30:23 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM <do_not_reply@GIOC.nsstc.nasa.gov> The Fermi GBM team reports the detection of a likely LONG GRB At 22:12:10 UT on 2 Jan 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240102B (trigger 725926335.090798 / 240102925). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 338.1, Dec = 46.5 (J2000 degrees, equivalent to J2000 22h 32m, 46d 30'), with a statistical uncertainty of 1.0 degrees. The angle from the Fermi LAT boresight is 3.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240102925/q...
