TITLE: GCN CIRCULAR NUMBER: 35682 SUBJECT: GRB 240205B: Fermi GBM Final Real-time Localization DATE: 24/02/05 22:23:35 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 22:13:08 UT on 5 Feb 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240205B (trigger 728863993.169242 / 240205926). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 352.0, Dec = -53.0 (J2000 degrees, equivalent to J2000 23h 27m, -53d 00'), with a statistical uncertainty of 1.0 degrees. The angle from the Fermi LAT boresight is 110.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240205926/q...
