Summer moon

For those in the northern hemisphere:

Summer Moon Illusion

June 27, 2007: Sometimes you can't believe your eyes. This weekend is one of those times.

On Saturday night, June 30th, step outside at sunset and look around. You'll see a giant moon rising in the east. It looks like Earth's moon with the usual craters and seas, but something's wrong. This full moon is strangely inflated. It's huge!

You've just experienced the Moon Illusion.
