NASA : The X-Ray Sun Over 5.5 Years.

Behold five and a half years worth of full-sun observations from XRT. A
dramatic illustration of the solar cycle, this movie begins about one
year before the first reversed-polarity sunspot ushered in the current
cycle on January 8, 2008. The solar cycle is a periodic variation in the
Sun's activity that is caused by the gradual 'tangling' and eventual
reversal of its magnetic field.
