Solar Tsunami

When one of my patients told me about the Space Weather website and e-newsletter I checked it out and signed up. At first, the newsletter was more annoying than interesting, showing up almost daily with odd tidbits. But then, every once in a while I get one like this, the Solar Tsunami, with a video worth watching. (Check the Space Weather archives for Dec. 9, 2006) Space is so fascinating that I can't unsubscribe to the newsletter, even if I just delete four-out-of-five.
