The “Super moon” as astrologer Richard Nolle coined the phrase, is when the moon is a new or full moon at 90% percent or greater of its closest perigee to Earth. The event will happen on Saturday (May 5) at 11:35 p.m. EDT. The moon will swing in 221,802 miles (356,955 kilometers) from our planet, offering sky-watchers a spectacular view of an extra-big, extra-bright moon.
This term has recently been picked up by astronomers as well. An extreme “SuperMoon” is when the moon is full or new as well as at its 100% greater mean perigee (closest) distance to earth.the moon’s perigee coincide with full moon this month. This perigee will be the nearest to Earth of any this year, as the distance of the moon’s close approach varies by about 3 percent. This happens because the moon’s orbit is not perfectly circular.
Can this Super Moon contribute to extreme weather?
While some speculate what effects the moon can have on earth. One can look back on some of the recent supermoons.
The supermoon that occurred on January 10th, 2005, was right around the time of the 9.0 Indonesia earthquake.
The supermoon that occurred on March 19th, 2011, was right around the time of the 9.2 Japan earthquake.
So will there be another large earthquake around this supermoon? Maybe a large volcanic eruption? I guess we will have to wait and see.
What are the actual chances?
Astronomer and lecturer David Reneke claims there’s more cause for alarm about the extent of human paranoia than any sort of impending apocalypse.
“If you try hard enough you can chronologically associate almost any natural disaster/event to anything in the night sky … comet, planet, sun,” he said.
“Remember in the past, planetary alignments were going to pull the sun apart. It didn”t. Astrologers draw a very long bow most times. Normal king tides are about all I would expect out of this SuperMoon prediction.”
However, the normal tides around the world will be particularly high and low. At perigee, the moon will exert about 42 percent more tidal force than it will during its next apogee two weeks later.
To view this weekend’s super moon to best effect, look for it just after it rises or before it sets, when it is close to the horizon. There, you can catch a view of the moon behind buildings or trees, an effect which produces an optical illusion, making the moon seem even larger than it really is.
