  "body": "The Fermi GBM team reports the detection of a likely SHORT GRB\n\nAt 07:05:40 UT on 18 Jul 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250718B (trigger 774515145.094648 / 250718296).\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 233.0, Dec = -26.0 (J2000 degrees, equivalent to J2000 15h 31m, -26d 00'), with a statistical uncertainty of 20.3 degrees.\n\nThe angle from the Fermi LAT boresight is 119.0 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250718296/quicklook/glg_skymap_all_bn250718296.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/bn250718296/quicklook/glg_healpix_all_bn250718296.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250718296/quicklook/glg_lc_medres34_bn250718296.gif\n",
