  "body": "The Fermi GBM team reports the detection of a likely LONG GRB\n\nAt 10:22:10 UT on 14 Aug 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250814B (trigger 776859735.510984 / 250814432).\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 80.1, Dec = 24.6 (J2000 degrees, equivalent to J2000 05h 20m, 24d 36'), with a statistical uncertainty of 4.6 degrees.\n\nThe angle from the Fermi LAT boresight is 132.0 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250814432/quicklook/glg_skymap_all_bn250814432.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/2025/bn250814432/quicklook/glg_healpix_all_bn250814432.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250814432/quicklook/glg_lc_medres34_bn250814432.gif\n",
