<B> Explanation: </B>
Every eleven years, our Sun goes through a solar cycle.
A complete
<A href="http://en.wikipedia.org/wiki/Solar_cycle">solar cycle</A>
has now been imaged by the sun-orbiting

spacecraft</A>,
celebrating the 12th anniversary of its launch yesterday.
A <A href="http://solarscience.msfc.nasa.gov/SunspotCycle.shtml">solar
cycle</A>
is caused by the changing
<A href="http://solar.physics.montana.edu/YPOP/Spotlight/Magnetic/what.html">magnetic field</A> of the Sun, and varies from

<A href="http://antwrp.gsfc.nasa.gov/apod/ap071106.html">flare phenomena</A> are most frequent,
to solar minimum, when such activity is relatively infrequent.
Solar minimums occurred in 1996 and 2007, while the last solar maximum
occurred in 2001.
