I love effects like this. A while ago, I read about all kinds of them, including glories. I'm not sure of the info source though. Wikipedia has a list: Category:Atmospheric optical phenomena
I also found this site: Atmospheric optics: Ice crystal halos
Here's another: Atmospheric Optics
You can see the Current Auroral Oval at SpaceWeather.com. Scroll down the page, look on the left, you'll find it. Lots of other info at this site.
