  "body": "The Fermi GBM team reports the detection of a likely SHORT GRB\n\nAt 00:28:01 UT on 7 Sep 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260907A (trigger 810433686.93629 / 260907019).\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 22.4, Dec = -39.0 (J2000 degrees, equivalent to J2000 01h 29m, -39d 00'), with a statistical uncertainty of 8.4 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/bn260907019/quicklook/glg_skymap_all_bn260907019.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/bn260907019/quicklook/glg_healpix_all_bn260907019.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260907019/quicklook/glg_lc_medres34_bn260907019.gif\n"
