Tempesta (TeleSpazio) report on behalf of\nthe AGILE Team:\n\nThe AGILE satellite detected the GRB 231215A at T0 = 2023-12-15\n09:47:17.8 s (UTC), reported by Swift (GCNs #35343, #35345, #35357),\nMondy (GCN #35349), MITSuME (GCN #35351), Astrosat (GCN #35352),\nHMT (GCN #35353), GROWTH (GCN #35354).\n\nThe event lasted about 12 s and it released a total number of 10990\ncounts in the MCAL detector RM (above a background rate of 548 Hz)\nand 49280 counts in the AC-Top detector RM (above a background\nrate of 2741 Hz). The AGILE ratemeters light curves can be\nfound at\n\nhttp://www.agilescienceapp.it/notices/GRB231215A_AGILE_RM_ND.png .\n\nThe event also triggered a high time resolution MCAL data acquisition,\nfrom T0-22 s s to T0+10 s (UTC), and released 8436 counts in the\ndetector, above a background rate of 510 Hz.\nThe MCAL light curve can be found at\n\nhttp://www.agilescienceapp.it/notices/GRB231215A_086695_629718437.810000.png .\n\nAt the T0, the event was 148 deg off-axis.\nAdditional analysis of AGILE data is in progress.
