Abstract

The AGILE satellite detected the long GRB 210531A at T0 = 2021-05-31 12:00:02.66 +/- 0.01 s (UTC), reported by Fermi/GBM (Trigger no. 644155206) and BALROG (GCN #30105). 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 35 s and it released a total number of 9650 counts in the SA detector (above a background rate of 90 Hz), 53900 counts in the MCAL detector (above a background rate of 1400 Hz), and 151900 counts in the AC detector (above a background rate of 3780 Hz). The AGILE ratemeter light curves can be found at http://www.agilescienceapp.it/notices/GRB210531A_AGILE_RM.png . The event also triggered a partial high time resolution MCAL data acquisition. 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....
