This comparision shows that Saturn has incredible changed concerning  belts and zones-structure,since 2004 until March 2006.

-The polar region,has totally changed, both the structure and the color is different.

-The STeZ as well as the STB has changed al lot.Especially the STB was
much smaller but also much more contrasty in 2004.The STB in the 2006-image seems to be 
as broad as the STeZ or the STrZ.

-The SEBn seems double-colored in 2004, with a tan northern edge,and a bluish southern edge.
in 2006, the SEBn is clearly tinner comared to 2004.

-not much changed seems the EZ/EB region.
