Tonight's full moon is going to be the closest to the earth of all of 2009. It's actually 50 000 km closer to our planet than usual (that is about 30 000 miles for those who don't know the metric system) and because of that, the moon is supposedly gonna look 30% brighter and about 15% bigger.
So if the clouds aren't in your way, I hope you look up and enjoy the view that is shining from above.
