Abstract
The AGILE satellite detected the long GRB 210511B at T0 = 2021-05-11 11:26:37 s (UTC), reported by Fermi/GBM (GCN #29988) and GECAM (GCN #29990). The burst is 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 ~12 s and released a total number of 2120 counts in the SA detector (above a background rate of 64 Hz), 15630 counts in the MCAL detector (above a background rate of 1260 Hz), and 48375 counts in the AC detector (above a background rate of 3865 Hz). The AGILE ratemeter light curves can be found at http://www.agilescienceapp.it/notices/GRB210511_AGILE_RM.png . Additional analysis of AGILE data is in progress....
