  "body": "The Fermi GBM team reports the detection of a likely LONG GRB\n\nAt 12:58:03 UT on 24 Nov 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 251124a (trigger 785681888.46989 / 251124540), which has also been reported in GCN 42820. An interruption in the automated pipeline caused the automated circular to be distributed later than normal.\n\nThe on-ground automated localization is consistent with the location in GCN 42820.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn251124540/quicklook/glg_skymap_all_bn251124540.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/bn251124540/quicklook/glg_healpix_all_bn251124540.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn251124540/quicklook/glg_lc_medres34_bn251124540.gif",
