TITLE: GCN CIRCULAR NUMBER: 44261 SUBJECT: GRB 260411A: Fermi GBM Final Real-time Localization DATE: 26/04/11 06:46:58 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 SHORT GRB At 06:36:28 UT on 11 Apr 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260411A (trigger 797582193.127706 / 260411275). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 153.6, Dec = 12.0 (J2000 degrees, equivalent to J2000 10h 14m, 12d 00'), with a statistical uncertainty of 9.6 degrees. The angle from the Fermi LAT boresight is 32.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260411275/q...
