Aurora

If you're up and it's not cloudy, go outside and look at the sky. The aurora is fading in and out over hour house in long pale streamers. (David was very skeptical, but I checked with Spaceweather, and they said sky watchers should be alert for the aurora tonight, because the Earth "has entered an unexpected solar wind stream that could spark a geomagnetic storm." It's not brightly colored out there, but it's very eerie and interesting.
