Twelve years is a high price to pay for a coke addiction.

But like anything in nature, sometimes they don't act like we expect them to.

After the next 24 hours it may start slowing down.

This event created a complete blackout of high-frequency communications on the day-lit side of Earth, which included the entire U.S. and basically anywhere the sun was shining at this time. Communications used by emergency services along the Gulf Coast may have experienced problems due to this flare. Low-frequency navigation systems may also have experienced a period of significant degradation.

Sometimes satellites can be damaged beyond repair.

It's not anything you can see, but it is something our instruments can track.

Satellites live and breathe in space; they are very vulnerable to solar activity. They affect our banking systems, our TVs and cell phones, all the luxuries of life.

This particular region (on the sun) is just now reaching the center of the sun. It's just now getting into the bull's-eye.

This flare, the fourth largest in the last 15 years, erupted just as the ... sunspot cluster was rotating onto the visible disk of the sun.
