TITLE: GCN CIRCULAR NUMBER: 35939 SUBJECT: GRB 240317A: Fermi GBM Final Real-time Localization DATE: 24/03/17 09:54:24 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 09:43:55 UT on 17 Mar 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240317A (trigger 732361440.302272 / 240317405). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 223.9, Dec = 19.1 (J2000 degrees, equivalent to J2000 14h 55m, 19d 06'), with a statistical uncertainty of 4.5 degrees. The angle from the Fermi LAT boresight is 75.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240317405/q...
