TITLE: GCN CIRCULAR NUMBER: 45081 SUBJECT: GRB 260705B: Fermi GBM Final Real-time Localization DATE: 26/07/06 00:19:12 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 22:46:36 UT on 5 Jul 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260705B (trigger 804984401.559966 / 260705949). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 68.5, Dec = -30.8 (J2000 degrees, equivalent to J2000 04h 33m, -30d 48'), with a statistical uncertainty of 3.0 degrees. The angle from the Fermi LAT boresight is 77.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260705949/q...
