  "body": "The Fermi GBM team reports the detection of a likely LONG GRB.\n\n\"At 14:00:55.64 UT on 07 June 2025, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 250607A (trigger 770997660/250607584).\n\nThe on-ground calculated location, using the Fermi GBM trigger data,\nis RA = 243.84, Dec = -24.71 (J2000 degrees, equivalent to J2000 16h 15m, -24d 42'),\nwith a statistical uncertainty of 10.15 degrees.\n\nThe angle from the Fermi LAT boresight is 90 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250607584/quicklook/glg_skymap_all_bn250607584.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/bn250607584/quicklook/glg_healpix_all_bn250607584.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250607584/quicklook/glg_lc_medres34_bn250607584.gif\""
