Using radio, X-ray and optical observations, we present evidence formorphological changes due to efficient cosmic ray ion acceleration in thestructure of the southeastern region of the supernova remnant SN 1006. SN 1006has an apparent bipolar morphology in both the radio and high-energy X-raysynchrotron emission. In the optical, the shock front is clearly traced by afilament of Balmer emission in the southeast. This optical emission enables usto trace the location of the blast wave (BW) even in places where thesynchrotron emission from relativistic electrons is either absent or too weakto detect. The contact discontinuity (CD) is traced using images in thelow-energy X-rays (oxygen band) which we argue reveals the distribution ofshocked ejecta. We interpret the azimuthal variations of the ratio of radiibetween the BW and CD plus the X-ray and radio synchrotron emission at the BWusing CR-modified hydrodynamic models. We assumed different azimuthal profilesfor the injection rate of particles into the acceleration process, magneticfield and level of turbulence. We found that the observations are consistentwith a model in which these parameters are all azimuthally varying, beinglargest in the brightest regions.
