TITLE: GCN CIRCULAR NUMBER: 35927 SUBJECT: GRB 240315A: Fermi GBM Final Real-time Localization DATE: 24/03/15 11:18:06 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 11:07:29 UT on 15 Mar 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240315A (trigger 732193654.441586 / 240315464). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 199.5, Dec = 21.9 (J2000 degrees, equivalent to J2000 13h 18m, 21d 53'), with a statistical uncertainty of 14.1 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/2024/bn240315464/q...
