AGILE Team:
The AGILE satellite detected the long burst GRB 200503A at T0 = 2020-05-03
05:01:44 (UT), reported by AstroSat CZTI (GCN #27680, Gupta et al.).
The event is visible in the scientific ratemeters of the SuperAGILE (SA;
20-60 keV), Anti-Coincidence (AC, 50-200 keV), and MiniCALorimeter (MCAL;
0.4-100 MeV) detectors. The burst light curve shows a multi-peaked time
profile that lasted ~25 s. The event released 3700 counts in the AC
ratemeters (above a background of ~3500 Hz), 1800 counts in the MCAL
ratemeters (above a background of ~2600 Hz), and 560 counts in the SA
ratemeters (above a background of 40 Hz). The ratemeters light curves can
be found at http://www.agilescienceapp.it/notices/RM_GRB200503A.png .
Additional analysis of AGILE data is in progress.
