In November 2010, the blazar 3C454.3 flared to extraordinary brightness. Luckily for us, it was just a few days before the visibility window for Herschel infrared observations opened. We present multiwavelength data obtained from November 2010 through January 2011, centered on our Target of Opportunity Herschel observations at five submillimeter and far-infrared bands. We combined the Herschel data with Fermi LAT gamma-ray data, Swift X-ray, ultraviolet and optical data, SMA millimeter data, optical and near-infrared data and other ground-based data to form a series of multiwavelength spectral energy distributions spanning nearly two months. Multiwavelength light curve analysis and modelling allow us to quantify time-dependent relationships between synchrotron-emitting charged particle distributions, seed photons, the inverse-Compton gamma-ray emission and the jet physical conditions as the flare evolved.
Funding has been provided by NASA through grants from the US Herschel Science Center and the Fermi Guest Investigator Program.
