  "body": "The Fermi GBM team reports the detection of a likely LONG GRB\n\nAt 12:08:46 UT on 23 Dec 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241223A (trigger 756648531.631546 / 241223506).\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 159.9, Dec = -34.8 (J2000 degrees, equivalent to J2000 10h 39m, -34d 47'), with a statistical uncertainty of 1.0 degrees.\n\nThe angle from the Fermi LAT boresight is 67.0 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn241223506/quicklook/glg_skymap_all_bn241223506.png\n\nThe HEALPix FITS file, including the estimated localization systematic, can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn241223506/quicklook/glg_healpix_all_bn241223506.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn241223506/quicklook/glg_lc_medres34_bn241223506.gif\n\n",
