July's full moon is known as the Buck Moon because during this time of year a bucks antlers are in full growth mode. Other names for this full moon include the Ripe Corn Moon and the Thunder Moon.
This full moon will also be the longest total lunar eclipse of the 21st century. You may hear it referred to as the Blood Moon Eclipse because of the red or ruddy brown shade it will turn during the eclipse. You won't be able to see this event from North America, but you can take a look at a live feed on an astronomy site like Slooh if you are interested.
