AGILE extraordinary detection from the blazar 3C 454.3

Starting on Nov. 17, 2010 (see ATel # 3034) the AGILE satellite detected another extraordinary gamma-ray flare from the blazar 3C 454.3 that we are calling “Crazy Diamond” for the unpredictable variability of its emission. This gamma-ray flare is the most intense and prolonged one (see ATel # 3043) ever detected, and transformed 3C 454.3 into the brightest gamma-ray source in the sky.
