Biggest full moon of 2009

This morning when I work up, it was a clear sky, and the moon was very bright. To me, the moon this morning was the same size but definitely brighter. It was an amazing view. I'll have to post a picture of it tonight if the sky is clear. But I just read this on space.com about this morning moon sighting: http://www.space.com/spacewatch/090109-biggest-full-moon-2009.html

Did you read the last part to this article? What did you think about it?

I thought this was the most interesting bit. (I knew it, but it's such an easy way to reveal the illusion!)

"At moonrise, the moon will appear even larger than it will later in the night when it's higher in the sky. This is an illusion that scientists can't fully explain. Some think it has to do with our perception of things on the horizon vs. stuff overhead.

Try this trick, though: Using a pencil eraser or similar object held at arm's length, gauge the size of the moon when it's near the horizon and again later when it's higher up and seems smaller. You'll see that when compared to a fixed object, the moon will be the same size in both cases."

Actually, the moon's always "out." You can only see the moon because it reflects sunlight. And it's easier to see at night, when the sky is dark and doesn't wash out the reflected light.

Here's another answer.
