TITLE: GCN CIRCULAR NUMBER: 43417 SUBJECT: GRB 260115A: Fermi GBM Final Real-time Localization DATE: 26/01/15 17:57:28 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 17:46:45 UT on 15 Jan 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260115A (trigger 790192010.88085 / 260115741). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 110.2, Dec = 3.3 (J2000 degrees, equivalent to J2000 07h 20m, 3d 17'), with a statistical uncertainty of 5.1 degrees. The angle from the Fermi LAT boresight is 83.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260115741/q...
