 note = {Astrophysics with All-Sky X-Ray observations: 3rd International MAXI Workshop (RIKEN, 10-12 June 2008), The spectrum of blazars span over 20 decades from radio to gamma rays. To clarify a variety of physical phenomena of the blazar jets, a blazar must be monitored in multiwavelengths and simultaneously. We succeeded in simultaneous multiwavelength observation of a blazar 3C 454.3, a QHB (quasar-hosted blazar) at z = 0.859. It also belongs to the brightest quasar class, with its luminosity reaching 10(exp 48) erg/s. A huge gamma-ray flare of 3C 454.3 was reported by the AGILE satellite on November 2nd through December 1st, 2007. We proposed a ToO observation with the Suzaku satellite, which was approved and performed on Dec 5, 6. At the same time, we were monitoring its optical magnitudes in three colors (g', Rc, Ic) using the MITSuME Telescope at the ICRR Akeno Observatory, Yamanashi, Japan. Its R band magnitude increased from R=16 up to R=13.4 on December 1. We present the spectral energy distribution based on this multiwavelength observation, and discuss the emission models., Physical characteristics: Original contains color illustrations, 資料番号: AA0064306042, レポート番号: JAXA-SP-08-014E},
