TITLE: GCN CIRCULAR NUMBER: 35641 SUBJECT: GRB 240127A: Fermi GBM Final Real-time Localization DATE: 24/01/27 05:01:10 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 04:50:40 UT on 27 Jan 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240127A (trigger 728023845.52457 / 240127202). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 299.9, Dec = -62.8 (J2000 degrees, equivalent to J2000 19h 59m, -62d 47'), with a statistical uncertainty of 29.9 degrees. The angle from the Fermi LAT boresight is 129.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240127202/q...
