Tonight is the last night (of the nights of May 25-27, 2021) that one on planet earth may be able to observe such a full supermoon (supermoon, lunar eclipse, and blood moon coincide) until 2034, lunar eclipse that coincides with the moon’s closest approach to Earth, making it a “supermoon” eclipse that will turn the moon reddish, aka a “blood moon.” (The dates of this eclipse span two days because the area it will be visible spans the international date line). The supermoon can be seen across the world while the blood moon or supermoon eclipse can be seen in parts of western United States, Canada, Mexico, parts of Central and South America, Australia, New Zealand, East Asia, Antarctica, and the Pacific Islands.
Let’s take a look at the wikipedia page on Lunar eclipse, in italics, below:
A lunar eclipse occurs when the Moon moves into the Earth’s shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, and only on the night of a full moon. The type and length of a lunar eclipse depend on the Moon’s proximity to either node of its orbit.
A totally eclipsed Moon is sometimes called a blood moon for its reddish color, which is caused by Earth completely blocking direct sunlight from reaching the Moon. The only light reflected from the lunar surface has been refracted by Earth’s atmosphere. This light appears reddish for the same reason that a sunset or sunrise does: the Rayleigh scattering of bluer light.
Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. A total lunar eclipse can last up to nearly 2 hours, while a total solar eclipse lasts only up to a few minutes at any given place, because the Moon’s shadow is smaller. Also unlike solar eclipses, lunar eclipses are safe to view without any eye protection or special precautions, as they are dimmer than the full Moon.
The timing depends a lot on what time zone you are in, relative to what is called Universal Coordinated Time (effectively the hour in Greenwich, England). In Asia, the eclipse occurs near moonrise in the evening. On the west coast of the Americas, the eclipse happens in the early morning hours, near moonset. The best viewing will be in between those two extremes: Australia, New Zealand, Hawaii, the islands of the South Pacific and southwestern Alaska.
Skywatchers are in for a treat on Wednesday when Super Blood Moon will be visible in some parts of the world. A phenomenon that occurs only when a lunar eclipse co-insides with the moon, in the video published on May 26, 2021, “Super Blood Moon 2021: Lunar trifecta occurring for first time in 6 years | World News | WION English “, below:
When the full moon is at its closest point to the Earth, it’s called a supermoon. May’s full moon is also known as the “flower moon,” and Tuesday night’s supermoon looked like it was turning a dark red color because it took place at the same time as a lunar eclipse, making the spectacle a “super flower blood moon.” CBS News correspondent Laura Podesta reports, in the video published on May 26, 2021, “Rare “super flower blood moon” seen around the world“, below:
Kiwi skygazers were among the first in the world to catch a glimpse of the much-anticipated 2021 blood supermoon, in the video published on May 26, 2021, “How often does it occur? The 2021 blood moon explained | Newshub“, below:
Ian Griffin said tonight’s eclipse will be a beautiful sight and one that parents should get their children up for, in the video published on May 25, 2021 , “Tonight’s super blood moon worth getting kids up for, astronomer says“, below:
Jendy Harper tracked down some astro photographers to see who got the best shot, in the video published on May 27, 2021, “Blood moon a showstopper for those who got a glimpse of it“, below:
Let’s see what wikipedia has to say about Supermoon , in italics, below:
A supermoon is a full moon or a new moon that nearly coincides with perigee—the closest that the Moon comes to the Earth in its elliptic orbit—resulting in a slightly larger-than-usual apparent size of the lunar disk as viewed from Earth. The technical name is a perigee syzygy (of the Earth–Moon–Sun system) or a full (or new) Moon around perigee.[a] Because the term supermoon is astrological in origin, it has no precise astronomical definition.
The real 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 like earthquakes and volcanic eruptions, but no such link has been found.
The opposite phenomenon, an apogee syzygy or a full (or new) Moon around apogee, has been called a micromoon.
Of the possible 12 or 13 full (or new) moons each year, usually three or four may be classified as supermoons, as commonly defined.
The most recent full supermoon occurred on May 26, 2021, and the next one will be on June 24, 2021.
The supermoon of November 14, 2016 was the closest full occurrence since January 26, 1948 and will not be surpassed until November 25, 2034.
The closest full supermoon of the 21st century will occur on December 6, 2052.
A full moon at perigee appears roughly 14% larger in diameter than at apogee. Many observers insist that the moon looks bigger to them. This is likely due to observations shortly after sunset when the moon is near the horizon and the moon illusion is at its most apparent.
While the moon’s surface luminance remains the same, because it is closer to the earth the illuminance is about 30% brighter than at its farthest point, or apogee. This is due to the inverse square law of light which changes the amount of light received on earth in inverse proportion to the distance from the moon. A supermoon directly overhead could provide up to 0.36 lux.
Claims that supermoons can cause natural disasters, and the claim of Nolle that supermoons cause “geophysical stress”, have been refuted by scientists.
Despite lack of scientific evidence, there has been media speculation that natural disasters, such as the 2011 Tōhoku earthquake and tsunami and the 2004 Indian Ocean earthquake and tsunami, are causally linked with the 1–2 week period surrounding a supermoon. A large, 7.5 magnitude earthquake centred 15 km north-east of Culverden, New Zealand at 00:03 NZDT on November 14, 2016, also coincided with a supermoon. Tehran earthquake on May 8, 2020, also coincided with a supermoon.
Scientists have confirmed that the combined effect of the Sun and Moon on the Earth’s oceans, the tide, is greatest when the Moon is either new or full. and that during lunar perigee, the tidal force is somewhat stronger, resulting in perigean spring tides. However, even at its most powerful, this force is still relatively weak, causing tidal differences of inches at most.
A supermoon, the biggest and brightest full moon of the year, coincides with a total lunar eclipse making the Moon appear red over the skies of Honolulu, in the video published on May 26, 2021, “LIVE: Supermoon is seen in the skies of Honolulu, Hawaii“, below:
The Australian Quantas even provided a special flight for a closer view of the rising supermoon: On 26 May 2021, Qantas offered a one-off exclusive Scenic flight from Sydney to Sydney! The flight departed Sydney at 7.40pm, cruising at 43000ft, the flight offered a closer view of the rising of the supermoon which also happens to be a total lunar eclipse than anyone else on the ground, in the video published on May 27, 2021, “Quantas B787 Dreamliner Supermoon Scenic Flight from Sydney to Syndey – Fly me to the moon!“, below:
