Abstract

On its 15th birthday, the AGILE satellite detected the long GRB 220423A at T0 = 2022-04-23 14:14:14 (UTC), reported by INTEGRAL SPI-ACS (trigger no.9870) and CALET (trigger no.1334758343). 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 20 s and it released a total number of 2150 counts in the SA detector (above a background rate of 75 Hz), 36645 counts in the MCAL detector (above a background rate of 1410 Hz), and 81820 counts in the AC detector (above a background rate of 3220 Hz). The AGILE ratemeter light curves can be found at http://www.agilescienceapp.it/notices/GRB220423A_AGILE_RM.png . Additional analysis of AGILE data is in progress.
