  "body": "S. Dalessi (UAH) reports on behalf of the Fermi GBM Team:\n\"At 11:01:14.31 UT on 7 June 2024, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 240607A (trigger 739450879/240607459). The final localization can be found in GCN 36634.\n\nThe GBM light curve consists of three bright pulses, with the bulk of the emission during the first 15 seconds, and continued emission out to roughly 30 seconds. This event is a very bright GRB (up to 10,000 counts/s over 50-300 keV) and follow-up across all wavelengths is encouraged.\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 17.8, Dec = -32.1 (J2000 degrees, equivalent to J2000 01h 11m, -32d 06'), with a statistical uncertainty of 1.0 degrees.\n(radius, 1-sigma containment,\nstatistical only; there is additionally a systematic\nerror which we have characterized as a core-plus-tail model, with 90% of\nGRBs having a 3.7 deg error and a small tail suffering a larger than 10 deg systematic error. [Connaughton et al. 2015, ApJS, 216, 32] ).\n\nThe angle from the Fermi LAT boresight is 109.0 degrees.",
