The moon over St John's was pretty full Saturday night, in fact bigger than it's been all year.
It's explained on NASA's website. The full moon's full phase will occur at sunset Sunday shortly before it reaches perigee, the closes point to Earth in the Moon's orbit.
This occurs about every 14 months. Some people refer to it as a super moon.
