TITLE: GCN CIRCULAR NUMBER: 35986 SUBJECT: GRB 240328A: Fermi GBM Final Real-time Localization DATE: 24/03/28 12:39:20 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 12:21:22 UT on 28 Mar 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240328A (trigger 733321287.517204 / 240328515). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 231.9, Dec = -3.8 (J2000 degrees, equivalent to J2000 15h 27m, -3d 47'), with a statistical uncertainty of 15.9 degrees. The angle from the Fermi LAT boresight is 91.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240328515/q...
