SUPERMOON 2013: Sunday's Moon 90% Close to Us, Disastrous Too [Video]
Full moons come and go each month, but supermoon comes only once a year, and this Sunday is the supermoon's time to glaze. On the other hand, astrologers are warning of natural disasters and astronomers say that the tides will shift because of the supermoon.
The June 2013 supermoon at 7 a.m. ET will be the largest supermoon this year-the moon will not only be bright and full, but also will be at its closest distance to Earth. It will also be the Summer Solstice, marking the beginning of summer.
If it is a clear night or day, take a step outside for the largest full moon that you will gaze until August 2014.
The moon orbits Earth every month, but the moon is at its closest point only once a year. To understand this better, Bruce McClure and Deborah Byrd at earthsky.org write that the supermoon's coming only once a year depends on how "month" is defined.
Bruce explained the definition of supermoon:
"...a new or full moon which occurs with the moon at or near (within 90% of) its closest approach to Earth in a given orbit (perigee). In short, Earth, moon and sun are all in a line, with moon in its nearest approach to Earth."
The supermoon will appear up to 14 percent bigger and 30 percent brighter than a normal moon. The wolves will be howling and the sky bright during the Supermoon, when the lunar orbit is closest to the Earth.
Astrologer Richard Nolle coined the term supermoon in 1979, also known as a perigree full moon.
Natural disasters during the Supermoon
While astronomers say the theory has been disproved, many natural disasters have occurred during supermoons in the past.
Hurricane Katrina and the 1992 earthquake in Turkey have also been linked to supermoons.
AccuWeather.com Astronomy Blogger Mark Paquette also pointed out in his blog that the devastating earthquake and tsunami that hit Indonesia on Dec. 26, 2004 occurred about two weeks prior to a "supermoon" on Jan. 10, 2005.
Nolle also stated that the last extreme "supermoon" occurred on Jan. 30, 2010, several weeks after the catastrophic earthquake that hit Haiti on Jan. 12, 2010.
The Japanese earthquake and tsunami from 2011 occurred immediately before a supermoon. After its occurrence, the earthquake left Christchurch, New Zealand in ruins on Feb. 22, 2011.
