  "body": "The Fermi GBM team reports the detection of a likely LONG GRB\n\nAt 01:51:34 UT on 25 Jul 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250725A (trigger 775101099.80868 / 250725077).\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 31.5, Dec = -85.4 (J2000 degrees, equivalent to J2000 02h 06m, -85d 24'), with a statistical uncertainty of 1.0 degrees.\n\nThe angle from the Fermi LAT boresight is 22.0 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250725077/quicklook/glg_skymap_all_bn250725077.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/bn250725077/quicklook/glg_healpix_all_bn250725077.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250725077/quicklook/glg_lc_medres34_bn250725077.gif\n",
