  "body": "The Fermi GBM team reports the detection of a likely SHORT GRB\n\n\"At 07:18:53.33 UT on 26 October 2025, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 251026B (trigger 783155938/251026305).\n\nThe on-ground calculated location, using the Fermi GBM trigger data,\nis RA = 132.32, Dec = -12.21 (J2000 degrees, equivalent to J2000 8h 49m, -12d 12'),\nwith a statistical uncertainty of 8.04 degrees.\n\nThe angle from the Fermi LAT boresight is 19 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn251026305/quicklook/glg_skymap_all_bn251026305.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/bn251026305/quicklook/glg_healpix_all_bn251026305.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn251026305/quicklook/glg_lc_medres34_bn251026305.gif\""
