Abstract:

　In this poster, we present the light curve data for the notable blazer object 3C 454.3 (z=0.859) in optical, X-ray and $gamma$-ray band. Since January 2008, we have been monitoring this object using the MITSuME, a 50 cm optical telescope, and detected several optical flares including extraordinary and simultaneous flares in the $gamma$-ray and optical bands in 2010 November. Additionally, the Monitor of All-sky X-ray Image (MAXI) has been observing 3C 454.3 continuously since August 2009. 　Using these data and $gamma$-ray flux observed with Fermi-LAT, we discuss correlations of flux variations between the energy bands.
