Back on December 8, a massive solar flare exploded out of a sunspot on the surface of the sun. While that may have caused some problems for satellites in orbit around the Earth, it had no other effect on us (except for some really cool Northern Lights).
The neat part is that the explosion sent a tsunami like shockwave across the surface of the sun.
This site has a video of the event (actually, it's a number of still photos put together into a video). http://www.spaceweather.com/index.cgi Select December 8, 2006 on the far right under "View Archives".
The video actually compresses eight minutes into a few seconds.
To give you a sense of scale, the Earth is roughly 1/1000 the size of the sun, or a little bit bigger than the spots on the right side of the image.
