AGILE detection of a burst (AGILE trigger no. 526185273)
Abstract
The AGILE satellite detected a long burst at T0 = 2020-09-03 02:34:34 (UT). The event is clearly visible in the scientific ratemeters of the SuperAGILE (SA; 18-60 keV), MiniCALorimeter (MCAL; 0.4-100 MeV), and AntiCoincidence (AC; 50-200 keV) detectors. The light curves show multiple emission episodes. The main episode lasted ~30 s and released 155300 counts in the SA detector (above a background rate of 62 Hz), 70500 counts in the MCAL detector (above a background rate of 1240 Hz), and 3850 counts in the AC detector (above a background rate of 3070 Hz). Several successive spikes follow the main episode. The AGILE ratemeters light curves can be found at: http://www.agilescienceapp.it/notices/burst200903023434_AGILE_RMs.png . The event also triggered a MCAL high time resolution data acquisition covering the first ~5 s of the GRB. The MCAL light curve can be found at http://www.agilescienceapp.it/notices/GRB_069402_526185273.882807.png . The event is compatible with the event reported by CALET (trigger ID 1283135531) and INTEGRAL SPI-ACS (trigger ID 8707,0). The burst might be related with GRB 200903B reported by Fermi-GBM (GCN #28352), occurring at 2020-09-03 02:42:40 (UT). Additional analysis of AGILE data is in progress.
