Abstract
AGILE detection of continued gamma-ray activity of the blazar 3C 454.3 During a dedicated Target of Opportunity repointing, triggered by the GLAST-LAT detection of 3C 454.3 above 100 MeV (ATEL #1628), the AGILE Gamma Ray Imaging Detector (GRID) detected 3C 454.3 in high state in the period between 2008-07-25 18 00 UT and 2008-07-28 03 00 UT. A preliminary maximum likelihood analysis shows a detection at a significance level above 5 sigma, with a source flux in excess of about 200e-8 ph/cm2/s for E>100 MeV.
