Go out. Look up.
There was an X-class solar flare on Valentine's Day, flinging a coronal mass ejection right at us, like a bullet out of a gun. Except faster. And much more powerful. It doesn't mean the end of the world, or even a zombie apocalypse, but it does mean some seriously cool auroras for the next several days. Don't know if it'll make it as far south as I live, but if you live in Minnesota or Canada, you might want to keep an eye on the sky for the next few nights. Could be the chance of a lifetime.
Here's what it looked like in Norway last night. Thanks to Space Weather for the pic and the info.
And thanks to John at One speed: Go for letting me bastardize his slogan.
