  "body": "The Fermi GBM team reports the detection of a likely SHORT GRB\n\nAt 18:27:03 UT on 2 Dec 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 251202B (trigger 786392828.111108 / 251202769).\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 347.2, Dec = -23.3 (J2000 degrees, equivalent to J2000 23h 08m, -23d 18'), with a statistical uncertainty of 4.5 degrees.\n\nThe angle from the Fermi LAT boresight is 92.0 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn251202769/quicklook/glg_skymap_all_bn251202769.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/bn251202769/quicklook/glg_healpix_all_bn251202769.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn251202769/quicklook/glg_lc_medres34_bn251202769.gif\n"
