Following the exceptional gamma-ray activity from the FSRQ 3C 454.3 (reported in the ATels #3034, #3041, and #3043), we have activated follow-up observations with the INTEGRAL satellite.
INTEGRAL has been pointing the source from 21 Nov, 2010, 16:45 UT to 24 Nov, 2010, 04:30 UT (Rev. 990), and has thus monitored the declining phase of the outburst (as observed by AGILE-GRID, ATel #3049).
The average flux detected by IBIS/ISGRI in the range 20-100 keV is 2.2e-10 erg/s/cm2, similar to that observed in May 2005 (Pian et al. 2005, A&A, 449, L21), and is slowly declining along the observation.
INTEGRAL will continue to monitor the source until 27 Nov, 2010.
