TITLE: GCN CIRCULAR NUMBER: 45037 SUBJECT: GRB 260624A: Fermi GBM Final Real-time Localization DATE: 26/06/24 16:09:12 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 15:54:14 UT on 24 Jun 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260624A (trigger 804009259.148196 / 260624663). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 54.1, Dec = -21.0 (J2000 degrees, equivalent to J2000 03h 36m, -21d 00'), with a statistical uncertainty of 4.4 degrees. The angle from the Fermi LAT boresight is 73.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260624663/q...
