What’s more this full moon marks the mid-point in a lunar cycle and indicates to skywatchers that there are just two weeks to go until the much-anticipated Great American Eclipse – first solar eclipse to cross the continental U.S. since 1979 – on August 21, 2017.
A full moon is always opposite the sun. That’s why it looks full to us. At full moon, the moon and sun are on a line, with Earth in between. It’s as though Earth is the fulcrum of a seesaw, and the moon and sun are sitting on either end of the seesaw. So as the sun sets in the west, the full moon rises. When the sun is below our feet at midnight, the full moon is highest in the sky. When the sun rises again at dawn, the full moon is setting.

Bottom line: A full moon looks full because it’s opposite Earth from the sun, showing us its fully lighted hemisphere or day side. The August 7-8 full moon will be partially eclipsed in Earth’s shadow. The eclipse is not visible from the Americas.
