Gotz \n(CEA/Saclay) report on behalf of the INTEGRAL SPI-ACS GRB team:\n\nThe three GRB reported on 2008-03-19 by the Swift team (GCN 7426, 7427,\n7442) have been independently detected by the SPI Anti-Coincidence \nSystem (ACS) on-board INTEGRAL.\n\nBurst         T0     duration    max counts in 50 msec\n------------------------------------------------------\nGRB080319A  05:45:41    10s        370\nGRB080319B  06:12:47    57s       5500\nGRB080319C  12:25:55    25s       1200\n\nThe SPI-ACS light curves are available (both as images and data files) \nat http://isdc.unige.ch/Soft/ibas/ibas_acs_web.cgi\n\nThe light curves, binned at 50 ms, are derived from 91 independent\ndetectors with different lower energy thresholds (mainly between 50 keV \nand 150 keV) and an upper threshold at about 100 MeV. The ACS response \nvaries as a function of the GRB incident angle. For these reasons we \ncaution that the count rates cannot be easily translated into physical \nflux units.",
