I thought that the solar cycle was 2 x 11 years with 2 changes in orientation of the "magnetic polarity" I need to go back to school.

Ulysses is an awesome spacecraft.

Hi Dee,

I am often wrong about this stuff, but what I was trying to say was that the polarity of sun spot pairs switches ever ~11 years (depending on the exact length of that cycle) while the North and South poles of the sun is thought to switch every ~22 years depending on the length of that cycle, but there is not complete agreement on the poles switching; while there seems to be real agreement that the sun spots switch polarity ~ every 11 years, but with some overlap of 11 year cycles.

Maybe some of the smart guys can clear this up for me, please.
