A feat of lunar synchronicity will create a Supermoon.
This happens when the moon is full and at the same time reaches its perigee -- the closest point to Earth in its orbit, according to NASA.
It makes for the biggest,
brightest moon of the year. A Supermoon, sometimes called a Super Full
Moon, is 14% larger and 30% brighter than most full moons, NASA says.
Taken separately, neither
a full moon nor the perigee is a big deal. The moon is full roughly
once a month, and it reaches its perigee just as often, but the next
time both will coincide will be August 2014.
