TITLE: GCN CIRCULAR NUMBER: 36544 SUBJECT: GRB 240527A: Fermi GBM Final Real-time Localization DATE: 24/05/27 07:18:53 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 07:07:25 UT on 27 May 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240527A (trigger 738486450.988348 / 240527297). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 307.6, Dec = -15.4 (J2000 degrees, equivalent to J2000 20h 30m, -15d 24'), with a statistical uncertainty of 10.3 degrees. The angle from the Fermi LAT boresight is 67.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240527297/q...
