  "body": "The Fermi GBM team reports the detection of a likely LONG GRB\n\nAt 14:45:37 UT on 23 Jul 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250723B (trigger 774974742.499166 / 250723615).\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 358.0, Dec = 50.6 (J2000 degrees, equivalent to J2000 23h 52m, 50d 36'), with a statistical uncertainty of 3.1 degrees.\n\nThe angle from the Fermi LAT boresight is 114.0 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250723615/quicklook/glg_skymap_all_bn250723615.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/bn250723615/quicklook/glg_healpix_all_bn250723615.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250723615/quicklook/glg_lc_medres34_bn250723615.gif\n",
