GRB 201216B: AGILE detection of a burst
Abstract
The AGILE satellite detected a burst at T0 = 2020-12-16 14:46:35.66 +/- 0.01 s (UTC). The burst is clearly visible in the AGILE scientific ratemeters of the SuperAGILE (SA; 20-60 keV), MiniCALorimeter (MCAL; 0.4-100 MeV), and AntiCoincidence (AC; 50-200 keV) detectors. The event lasted about ~10 s and it released a total number of 1600 counts in the SA detector (above a background rate of 100 Hz), 1500 counts in the MCAL detector (above a background rate of 1220 Hz), and 37500 counts in the AC detector (above a background rate of 3500 Hz). The AGILE ratemeter light curves can be found at http://www.agilescienceapp.it/notices/GRB_201216B_AGILE_RM.png . The event also triggered a partial high time resolution MCAL data acquisition, where it released ~2500 counts (in the 0.4-100 MeV energy range), above a background rate of 570 Hz. The MCAL light curve can be found at http://www.agilescienceapp.it/notices/GRB_070900_535214795.665353.png . The AGILE/MCAL detector is a CsI detector with a 4 pi FoV, sensitive in the energy range 0.4-100 MeV. Additional analysis of AGILE data is in progress.
