Well if it does erupt we'll be in for a great light show in the sky.
Sunspot Grows to 20 Times Size of Earth
A sunspot group aimed squarely at Earth has grown to 20 times the size of our planet and has the potential to unleash a major solar storm.
The amorphous mix of spots, together called Number 652, has been rotating across the Sun and growing for several days. On Friday, it sat at the center of the solar disk.
The Sun's last bout of intense storminess occurred last fall, when a string of 10 major flares over two weeks knocked out satellites, damaged others, and forced the FAA to reroute airlines away from exposed polar routes.
No one can say if this sunspot group will let loose with a major storm, but it has the characteristics of a potentially big event.
"The implications of this spot have scientists on the edge of their seats," NASA said in a statement Friday. "If the active region generates coronal mass ejections (CMEs), massive explosions with a potential force of a billion megaton bombs, it will be a fairly direct hit to Earth and its satellites and power grids."

But it looks pretty significant! Hopefully the sun will be there tommorow?
There are 3 categories: X-class flares are big; they are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. M-class flares are medium-sized; they generally cause brief radio blackouts that affect Earth's polar regions. Minor radiation storms sometimes follow an M-class flare. Compared to X- and M-class events, C-class flares are small with few noticeable consequences here on Earth.
