LANHAM, Md. (WNEW) — The second supermoon will be on display tonight, and will be the closest and largest full moon in 2014.
When the moon is full as it makes its closest pass to Earth, it becomes a “Supermoon,” and will be up to 31,000 miles closer to Earth than other full moons this year.
According to NASA, this weekend’s full moon will be 14-percent closer and 30-percent brighter than other full moons of the year.

The moon’s distance from the Earth varies slightly as it circles the Earth in its slightly elliptical orbit, according to CBS News. At its closest, called “perigee,” as on Sunday, the moon will appear slightly larger than average, though this difference is not visible to the naked eye.
However, the close moon does have an effect on the ocean tides, which are higher than normal on the day of perigee and the three days following. Like the seasons, the tides lag slightly behind what geometry would suggest.
One way to take in the experience is around midnight, when your viewing location is at its minimum distance from the moon. However, the absolute best way to enjoy supermoon in all its glory is to stake out a spot with a clear view to the east, and watch for the moon creeping up into the sky around sunset.
