  "body": "The Fermi GBM team reports the detection of a likely LONG GRB\n\nAt 09:11:07 UT on 7 Apr 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260407A (trigger 797245872.223582 / 260407383).\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 71.4, Dec = 28.2 (J2000 degrees, equivalent to J2000 04h 45m, 28d 11'), with a statistical uncertainty of 2.1 degrees.\n\nThe angle from the Fermi LAT boresight is 61.0 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260407383/quicklook/glg_skymap_all_bn260407383.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/2026/bn260407383/quicklook/glg_healpix_all_bn260407383.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260407383/quicklook/glg_lc_medres34_bn260407383.gif\n",
