TITLE: GCN CIRCULAR NUMBER: 43785 SUBJECT: GRB 260219A: Fermi GBM Final Real-time Localization DATE: 26/02/19 14:18:05 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 14:04:53 UT on 19 Feb 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260219A (trigger 793202698.807012 / 260219587). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 167.4, Dec = 9.6 (J2000 degrees, equivalent to J2000 11h 09m, 9d 35'), with a statistical uncertainty of 2.7 degrees. The angle from the Fermi LAT boresight is 97.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260219587/q...
