A rare event happens on the very 1st day of 2014 a “Supermoon”. The term “Supermoon” is kind of made up term as it really just means perigee moon. That means the moon is at it’s closest approach to the Earth within it’s orbit. We will have the 1st of 2 “supermoon” on January 1st with a 2nd coming on January 30th 2014.
Richard Nolle, is credited with coining up with the term supermoon. He defines them as:
. . . a new or full moon which occurs with the moon at or near (within 90% of) its closest approach to Earth.
Now this moon won’t be seen because it’s a new moon. You can have a” supermoon” either when it’s full or new. In this case in January 2014 both the “supermoons” will be new moons. Meaning you won’t see them but they still have impacts on the Earth. Because the moon is so close it’s gravitational pull will be greater. Thus making tides in the ocean run higher or astronomical high tides as we call them. They always have a similar effect on the atmosphere. Full and new moons can make the atmosphere thicker or thinner which can intensify areas of low and high pressure. We sometimes refer to these as atmospheric tides.
This won’t be the only 2 “supermoons” in 2014, we will have a total of 5 during the year. The 2 in January then “super full moons” in July, August and September. The “super” full moon on August 10th, 2014 will be the closest of the year at 221,765 miles away from the Earth.
