Several months ago, I wrote a post about the supermoon that gathered a lot of attention. To read this post, please click here.
Anyway, in a couple of days, another supermoon will occur. A supermoon, by definition, is when the Earth, Moon and Sun are all in a line at the same time that the Moon is at its closest approach to Earth. To be a supermoon, the moon has to be either full or new, or else the “line” mentioned above would not be in effect. This supermoon will take place on Sept. 27.
Basically, the super moon causes an increase on the gravitational pull on the Earth by the two celestial bodies that influence the gravitational pull the most, the Sun and the Moon. When theses bodies are lined up, such as during a new or full moon, the two gravitational pulls of these two bodies act in concert together on the Earth. That is why the tides are astronomically higher during a full or new moon. When the Sun and Moon are not lined up, they cancel each other out somewhat. When the moon is at perigee (its closest pass to the Earth), the gravitational pull of the Moon on the Earth is also slightly stronger. So all of these facts cause an increased gravitational pull on the Earth during a supermoon.
Supermoons are not rare. At least two, or perhaps a half dozen, occur each year. So, this phenomenon is not unusual or unheard of.
Unashamedly, I am not an expert on the supermoon. Astrologer Richard Noelle coined the term in 1979 and is the “man” when it comes to all aspects of the supermoon. Please see this article about him and the supermoon by clicking here. You can also visit his terrific site by clicking here.
As mentioned before, some people believe that the supermoon may play a role in severe weather or seismic events. Daniel Vogler, AccuWeather Astronomy expert added, “There will as usual an increase in quakes with in the +-3 day window. If sunspot 1289 picks up intensity and facing us, Expect more of what happened in Canada.”
