Abstract
The AGILE Gamma Ray Imaging Detector (GRID) detected 3C 454.3 in high state in the period between 2008-06-15 10 46 UT and 2008-06-16 07 11 UT. Despite the fact that the source is currently more than 35 degrees off-axis, a preliminary maximum likelihood analysis shows a detection at a significance level of about 5 sigma, with a source flux in excess of 100e-8 ph/cm2/s at energies above 100 MeV.
