Last night I was driving to the grocery store at 9pm Mountain. Driving east to the store, I saw the biggest, best moon I'd ever seen. It was giant--three times its usual size. It was bright yellow. And it was hanging low just over the horizon, possibly explaining the size.
When I left the store at 9:45 the moon was higher, smaller and a simple white. In other words, a normal full moon. The moment was gone.
I didn't take a picture. But thanks to the magic of flickr, here's a picture of the August 2011 full moon.
Wow, I was about to post about how the size illusion is due to atmospheric distortion near the horizon as I remember that being the explanation I got at one point. But apparently that is false!

And apparently the real reason still isn't really settled:
