Astronomers have coined the term "Super Moon" which means a new or full moon at 90% or greater of its closest perigee to Earth. In 12 days, on March 19th, the moon will be at perigee (its closest position in its orbit to Earth). This will be the closest perigee in 18 years.
An "Extreme Super Moon" is when the moon is full or new as well as at its 100% greater mean perigee (closest) distance to earth. By this definition, this month's full moon on March 19th will all be "Extreme SuperMoons".
The largest effect will be on the tide which occurs at the full moon every month as the closer to the earth the moon orbits, so the effect on tides increases. A 5% increase in proximity makes about 20% difference in the power the moon exerts so those of us here in Jamaica Bay, especially West 12th Road, should anticipate stronger tides.
Lovely. I'm going to buy floaties for my vehicles.
