    Hi! Sunspots on our sun don't appear at the poles-- they have what is called a "butterfly" pattern, where the location of their appearance shifts from high (but not polar) latitudes to lower (equatorial) latitudes on the Sun as the solar cycle goes from activity (number of sunspots) maximum to minimum. You need to look at a picture to see why this makes a butterfly -- but basically the two hemispheres of the sun (north and south) make the two wings of the butterfly. See http://web.hao.ucar.edu/p.../slides/slide18.html However! Although our Sun doesn't have spots at the poles, other stars apparently do! Check out http://solarphysics.livin...age=articlesu25.html cheers, Sarah
