Following the detection by AGILE (ATel #3034) and Fermi-LAT (ATel #3041) of the dramatic gamma-ray flare from the Flat Spectrum Radio Quasar 3C 454.3 between November 16 and November 18, 2010, we report on its prolonged gamma-ray activity detected by AGILE.
For a 30-hour integration, from 2010-11-18 03:15 UT to 2010-11-19 09:15 UT, a preliminary quicklook maximum likelihood analysis of the AGILE-GRID data yields an average flux F = (58 +/- 6)e-6 ph/cm2/sec (E > 100 MeV), i.e., approximately the same peak flux reported by Fermi-LAT on a 18-hour time scale (from 2011-11-16 12:00 UT to 2011-11-17 06:00 UT, ATel #3041).
