In astronomy and astrology a perigee or "supermoon" is a full or new moon that coincides with a close approach by the Moon to the Earth, by wikipedia.
The super full Moon of March 19th was the biggest and closest full Moon of the past 18 years, lighting up the night sky from just 221,567 miles (356,577 kilometers) away. It might also be the most photographed full Moon.
Richard Nolle, source here, a noted astrologer who runs the website astropro.com, has famously termed the upcoming full moon at lunar perigee (the closest approach during its orbit) an "extreme supermoon."
When the moon goes super-extreme, Nolle says, chaos will ensue: Huge storms, earthquakes, volcanoes and other natural disasters can be expected to wreak havoc on Earth. (It should be noted that astrology is not a real science, but merely makes connections between astronomical and mystical events.)
