TITLE: GCN CIRCULAR NUMBER: 44346 SUBJECT: GRB 260419A: Fermi GBM Final Real-time Localization DATE: 26/04/19 07:20:17 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 07:09:40 UT on 19 Apr 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260419A (trigger 798275385.308626 / 260419298). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 317.4, Dec = -34.4 (J2000 degrees, equivalent to J2000 21h 09m, -34d 23'), with a statistical uncertainty of 2.3 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/bn260419298/q...
