Here is some information on a rather large full moon on the night of 10/25. Maybe it will help the Rockies with Game 2 of the World Series? Hey, after last night they could use all the help they can get!

Big Full Moon Tonight

Tonight’s full Moon (10/25/2007) is the biggest full Moon of the year. Some full Moons are genuinely larger than others...and tonight’s will be as much as 14% wider and 30% brighter than the other full Moons of 2007. The reason is that tonight’s full Moon will be occurring during "perigee"...or when in the Moon’s orbit around the Earth when it comes the closest. The Moon’s orbit is an ellipse with one side 30,000 miles closer to the Earth than the other. When the Moon is furthest from the Earth in its orbit...it is at "apogee". So when viewing tonight’s full Moon and it appears larger than normal...it is no illusion, it really is!
