Giuliani (INAF/IASF-Mi), report\non behalf of the AGILE Team:\n\nThe AGILE satellite detected the long GRB 210410A at T0 = 2021-04-10\n00:53:16.64 +/- 0.01 s (UTC), reported by Fermi/GBM (GCN #29777), Swift/XRT\n(GCN #29778), and Fermi/LAT (GCN #29781).\n\nThe burst is visible in the AGILE scientific ratemeters of the SuperAGILE\n(SA; 20-60 keV), MiniCALorimeter (MCAL; 0.4-100 MeV), and AntiCoincidence\n(AC; 50-200 keV) detectors. The event lasted ~15 s and released a total\nnumber of 1050 counts in the SA detector (above a background rate of 60\nHz), 29400 counts in the MCAL detector (above a background rate of 1200\nHz), and 72250 counts in the AC detector (above a background rate of 3320\nHz). The AGILE ratemeter light curves can be found at\nhttp://www.agilescienceapp.it/notices/GRB210410_AGILE_RM.png .\n\nThe event also triggered a partial high time resolution MCAL data\nacquisition, whose light curve can be found at:\nhttp://www.agilescienceapp.it/notices/072541_GRB_545100796.643050.png .\n\nAdditional analysis of AGILE data is in progress.
