GRB230812B: AGILE/MCAL detection
Abstract
The AGILE satellite detected the GRB 230812B at T0 = 2023-08-12 18:58:12 s (UTC), reported by Fermi (GCNs #34386, #34387, #34391, #34392), Swift (GCNs #34388, #34393, #34394, #34395, #34399, #34400) and MASTER (GCNs #34389, #34396). The event lasted about 8 s and it released a total number of 17046 counts in the MCAL detector (above a background rate of 590 Hz) and 97310 counts in the AC-Top detector (above a background rate of 3188 Hz). The AGILE ratemeters light curves can be found at http://www.agilescienceapp.it/notices/GRB230812B_AGILE_RM_ND.png . The event also triggered a high time resolution MCAL data acquisition, from T0 s to T0+2 s (UTC), and released 12643 counts in the detector, above a background rate of 561 Hz. The MCAL light curve can be found at http://www.agilescienceapp.it/notices/GRB230812B_084865_618951492.000000.png . At the T0, the event was 55 deg 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
