TITLE: GCN CIRCULAR NUMBER: 37759 SUBJECT: GRB 241010B: Fermi GBM Final Real-time Localization DATE: 24/10/10 18:00:35 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 17:49:55 UT on 10 Oct 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241010B (trigger 750275400.960368 / 241010743). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 319.1, Dec = 22.2 (J2000 degrees, equivalent to J2000 21h 16m, 22d 11'), with a statistical uncertainty of 9.6 degrees. The angle from the Fermi LAT boresight is 72.0 degrees.
