Circular_text TITLE: GCN CIRCULAR NUMBER: 36763 SUBJECT: GRB 240625B: Fermi GBM Final Real-time Localization DATE: 24/06/25 23:09:13 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 22:58:35 UT on 25 Jun 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240625B (trigger 741049120.43883 / 240625957). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 90.0, Dec = -11.1 (J2000 degrees, equivalent to J2000 06h 00m, -11d 05'), with a statistical uncertainty of 10.3 degrees. The angle from the Fermi LAT boresight is 87.0 degrees.
