TITLE: GCN CIRCULAR NUMBER: 43997 SUBJECT: GRB 260314A: Fermi GBM Final Real-time Localization DATE: 26/03/14 01:09:31 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 00:58:50 UT on 14 Mar 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260314A (trigger 795142735.353478 / 260314041). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 260.2, Dec = 62.9 (J2000 degrees, equivalent to J2000 17h 20m, 62d 53'), with a statistical uncertainty of 8.2 degrees. The angle from the Fermi LAT boresight is 59.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260314041/q...
