This article http://www.physorg.com/news/2011-06-big-edge-solar.html" [Broken] tells about discovery of magnetic bubbles at the edge of solar system. As I understand they are around 100AU from Sun and around the size of 1AU. That makes them roughly 3.6° angular size. Shouldn't these bubbles cause some effect in CMB? If they do then the effect should be discernible as it would undergo rather detectable paralax.
