Supermoon of November 13-14, 2016
Dear Friends & Neighbors,
(Please click on red links & note magenta)
Did you see the Supermoon on Sunday, Nov. 13 and Monday, Nov. 14, 2016? It is the closest moon to Earth in almost 70 years. We won’t see a supermoon like this until 2034. I couldn’t help myself and snapped quite a few photos with my iPhone7+ on Sunday night. But none of my photos could quite measure up to what was taken by NASA’s special camera above.
The name SuperMoon was coined by astrologer Richard Nolle in 1979, arbitrarily defined as:
…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.
Nolle also claimed that the moon causes “geophysical stress” during the time of a supermoon. Nolle never outlined why the 90% was chosen.
The term supermoon is not used within the astronomical community, which uses the term perigee-syzygy or perigee full/new moon. Perigee is the point at which the Moon is closest in its orbit to the Earth, and syzygy is when the Earth, the Moon and the Sun are aligned, which happens at every full or new moon. Hence, a supermoon can be regarded as a combination of the two, although they do not perfectly coincide each time.
A supermoon is the coincidence of a full moon or a new moon with the closest approach the Moon makes to the Earth on its elliptical orbit, resulting in the largest apparent size of the lunar disk as seen from Earth. The association of the Moon with both oceanic and crustal tides has led to claims that the supermoon phenomenon may be associated with increased risk of events such as earthquakes and volcanic eruptions, but the evidence of such a link is widely held to be unconvincing.
The Moon’s distance varies each month between approximately 357,000 and 406,000 kilometers (222,000 and 252,000 mi) due to its elliptical orbit around the Earth (distances given are centre-to-centre). A full moon at perigee is visually larger up to 14% in diameter (or about 30% in area) and shines 30% more light than one at its farthest point, or apogee.
On Monday (Nov. 14) at 6:15 a.m. EST, the moon will arrive at its closest point to the Earth in 2016: a distance of 221,524 miles (356,508 kilometers) away. This distance, which is measured from the center of the Earth to the center of the moon, is within 85 miles (137 km) of the moon’s closest possible approach to Earth; to be sure, this is an extreme perigee. This full moon will be the closest and brightest supermoon of 2016 but also the largest since 1948, according to Bob Berman, an astronomer at the Slooh Community Observatory (check out: live.Slooh.com), in a statement to Space.com. What’s more, the full moon won’t come this close to Earth again until Nov. 25, 2034, according to a statement from NASA. So, enjoy these photos and video.
