GRB 211219A: AGILE detection
Abstract
The AGILE satellite detected the long GRB 211219A at T0 = 2021-12-19 14:55:22 (UTC), reported by Fermi GBM (GCN #31265). The burst is clearly visible in the AGILE scientific ratemeters of the MiniCALorimeter (MCAL; 0.4-100 MeV) and AntiCoincidence (AC; 50-200 keV) detectors. The event lasted about 6.0 s and it released a total number of 7115 counts in the MCAL detector (above a background rate of 1240 Hz), and 18620 counts in the AC detector (above a background rate of 3450 Hz). The AGILE ratemeter light curves can be found at http://www.agilescienceapp.it/notices/GRB211219A_AGILE_RM.png . At the T0, the event was about 63° off-axis. Additional analysis of AGILE data is in progress. Automatic MCAL GRB alert Notices can be found at: https://gcn.gsfc.nasa.gov/agile_mcal.html.
