TITLE: GCN CIRCULAR NUMBER: 35949 SUBJECT: GRB 240318A: Fermi GBM Final Real-time Localization DATE: 24/03/18 03:01:31 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 02:51:01 UT on 18 Mar 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240318A (trigger 732423066.81932 / 240318119). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 275.1, Dec = -5.0 (J2000 degrees, equivalent to J2000 18h 20m, -5d 00'), with a statistical uncertainty of 4.8 degrees. The angle from the Fermi LAT boresight is 53.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240318119/q...
