They store a lot of energy, and when tangled they can suddenly snap, releasing that energy. Astronomers <a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/www.spaceweather.com\/glossary\/flareclasses.html\">classify flares<\/a> by the energy released in X-rays, from Classes A,B, and C (weak) to M (moderate) to X (yikes!). This one was an M9, which is on the low end of the M class. Powerful, but probably not enough to affect us here 150 million kilometers away. If anything, there may be a stronger than normal aurora in a day or two.<\/p><p>The Sun&rsquo;s activity waxes and wanes on a roughly 11 year cycle, and we&rsquo;re on the upswing of Cycle 24.
