Circular_text TITLE: GCN CIRCULAR NUMBER: 37481 SUBJECT: GRB 240913A: Fermi GBM Final Real-time Localization DATE: 24/09/13 03:32:17 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 03:21:41 UT on 13 Sep 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240913A (trigger 747890506.70684 / 240913140). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 68.7, Dec = 13.8 (J2000 degrees, equivalent to J2000 04h 34m, 13d 48'), with a statistical uncertainty of 6.0 degrees. The angle from the Fermi LAT boresight is 88.0 degrees.
