A Total Lunar Eclipse / Total Eclipse of the Moon occurs early Tuesday morning, well visible in North America (including Alaska and Hawaii), parts of northern and eastern Europe, Asia, and Australia, as well as much of South America, Arctic region, Antarctica, and from the Pacific, Atlantic, and Indian Oceans, weather-permitting. Live-stream web-casts of the event will be available, for areas of the world where the Eclipse is not visible, or where the weather is not amenable to viewing the Eclipse.
A Lunar Eclipse / Eclipse of the Moon is the only category of Eclipses which is safe to view with the unaided eyes (one-power), binoculars, and a telescope. While binoculars or a telescope can assist in seeing lunar details, a good view of such an Eclipse can be had by just using the unaided eyes.
Of course, a Lunar Eclipse / Eclipse of the Moon can only be observed, if the Moon has risen at a certain locale, weather-permitting. Near the end of this blog-post is an Internet link to a map(s) showing where such an Eclipse can be observed, and whether the entire Eclipse can be observed, or if only a portion of the Eclipse can be observed. Also, near the end of this blog-post is an Internet link to a U.S. Naval Observatory web-page, where you can plug-in your location to determine the times of moonrise and moonset.
Live-stream Web-casts of this Total Lunar Eclipse / Total Eclipse of the Moon will be available for observers not in a region where the Eclipse is visible in the sky, or where weather conditions make such an observation impossible (Internet links to these Live-stream Web-casts near the end of this blog-post).
A Lunar Eclipse / Eclipse of the Moon occurs when the orbit of the Moon brings our natural satellite into the Earth's shadow (shadow caused by the Earth completely blocking light from the Sun). The Earth's shadow, extending into Outer Space from the dark or night side of Earth, is divided into two sections: the dim Penumbra or Penumbral Shadow, which encircles the deeper Umbra or Umbral Shadow.
A Lunar Eclipse / Eclipse of the Moon always occurs near the time, and including the time, of a Full Moon. The Moon's orbit is slightly tilted, so most months at the Primary Moon Phase of Full Moon, the Moon moves above or below the Earth's shadow, with no Eclipse occurring.
A Total Lunar Eclipse / Total Eclipse of the Moon is when the Earth's deep shadow, or Umbra, completely envelops the Moon. Of course, "Totality" / Total Phase of a Total Lunar Eclipse / Total Eclipse of the Moon is the most impressive part of this type of Eclipse, what most people wait to see.
The Partial Phases of a Total Lunar Eclipse / Total Eclipse of the Moon, are when a piece of the Moon seems missing, as the Moon moves farther into the Earth's main shadow known as the Umbra, or as the Eclipse is ending and the Moon is further moving out of the Earth's Umbra.
Usually, a Total Lunar Eclipse / Total Eclipse of the Moon only occurs once every 2.5 years, approximately, as seen from someplace in the world. The last two happened on 2021 May 26 and on 2022 May 15 / 16.
However, the 2022 November 8 Eclipse will be the last Total Lunar Eclipse / Total Eclipse of the Moon until 2025 March 14. Although, Partial and Penumbral Lunar Eclipses / Eclipses of the Moon will still occur before 2025.
All eclipses come in pairs (a Solar Eclipse / Eclipse of the Sun comes a couple weeks before, or after, a Lunar Eclipse / Eclipse of the Moon), sometimes even in threes. In the current case, a Partial Solar Eclipse / Partial Eclipse of the Sun occurred early on the morning of 2022 October 25. An Internet link to the blog-post regarding the October 25 Eclipse is located near the end of this blog-post.
When the Earth's deep shadow, known as the Umbra, falls on only part of the Moon's surface, this is known as a Partial Lunar Eclipse / Partial Eclipse of the Moon. This is more easily visible, if you are in the right location and weather conditions are acceptable.
When the Earth's dim shadow, known as the Penumbra, falls on the Moon, it is called a Penumbral Lunar Eclipse / Penumbral Eclipse of the Moon. Because the Earth's shadow is dim in this case, this type of Eclipse is difficult to discern.
A Penumbral Lunar Eclipse / Penumbral Eclipse of the Moon, and the Penumbral Phases of the Total or Partial Lunar Eclipses / Eclipses of the Moon, are difficult to see, as the Moon moves into or out of the Earth's secondary shadow or Penumbra. In this case, one would not see any chunks or bites taken out of the Moon's disk, as one would see when the Moon moves into the Umbra shadow during the Partial Phases. Instead, if your eyes are very good, you may notice a slight dimming of the light coming from the Moon, as the Moon moves farther into the Penumbral Shadow.
Although no direct sunlight reaches the Moon during the Totality phase of a Total Lunar Eclipse / Total Eclipse of the Moon, the Earth's atmosphere refracts the sunlight around our planet allowing a portion of the sunlight to continue to be transmitted to the Moon. However, the refracted light reaching the Moon is primarily in the yellow, orange, and red portions of the electromagnetic spectrum (the Earth's atmosphere filters-out the violet, blue, and green colors), as with orange or red-tinted sunrises and sunsets (during such a Total Lunar Eclipse / Total Eclipse of the Moon, a person standing on the side of the Moon facing Earth could see all Earth sunrises and sunsets simultaneously, as they viewed the Earth in a Total Solar Eclipse / Total Eclipse of the Sun --- but, even on the Moon, a person would need to take strong precautions to ensure their eye-sight is not damaged by such a view). Hence, it is orange or red light that is reflected from the Moon back into your eyes during a Total Lunar Eclipse / Total Eclipse of the Moon.
Again, particularly during the middle of a Total Lunar Eclipse / Total Eclipse of the Moon, the Moon will not disappear from view but can be seen with an orange or reddish tint, what some call "blood red" (this is sometimes referred to as a “Blood Moon”). If the Earth had no atmosphere, likely no sunlight would reach the Moon during a Total Lunar Eclipse / Total Eclipse of the Moon, and there would be no "Blood Moon;" the Moon would seem to completely disappear.
Here are the major stages of this Total Lunar Eclipse / Total Eclipse of the Moon –--
Early Tuesday Morning, 2022 November 8 -
[Eastern Standard Time (EST) / Coordinated Universal Time (UTC)]
Note: A Lunar Eclipse / Eclipse of the Moon is the only type of Eclipse where the times of Eclipse are the same world-wide, when using Coordinated Universal Time. Everyone on the dark or night side of Earth can view, at least a portion of, this type of Eclipse in the sky, weather-permitting.
Penumbral Eclipse Begins: 3:01:52 a.m. EST / 8:01:52 UTC
Partial Eclipse Begins: 4:08:49 a.m. EST / 9:08:49 UTC
Total Eclipse Begins: 5:16:12 a.m. EST / 10:16:12 UTC
Time of Greatest Eclipse: 5:59:11 a.m. EST / 10:59:11 UTC
Primary Phase of Full Moon: 6:02 a.m. EST / 11:02 UTC
Total Eclipse Ends: 6:41:52 a.m. EST / 11:41:52 UTC
Partial Eclipse Ends: 7:49:24 a.m. EST / 12:49:24 UTC
Penumbral Eclipse Ends: 8:56:32 a.m. EST / 13:56:32 UTC
At the time of Greatest Total Lunar Eclipse / Total Eclipse of the Moon on November 8 at 6:02 a.m. EST / 11:02 UTC, the Moon will be 100 per-cent obscured by the Earth's Umbral Shadow. It may appear dark with a reddish or orange tint; some refer to this as a “Blood Moon.” In fact, the Moon's disk actually passes through the axis of Earth's Umbral Shadow, which means this will be a very deep and dark Eclipse.
And, at the time of Greatest Eclipse, the Moon is farther from the Earth than normal. In fact the Moon reaches the monthly point of apogee, in the lunar orbit, 5.8 days after the Eclipse. So, the Moon will appear a wee-bit smaller than it may appear at other times of the month.
During this Eclipse, the Moon is located in the direction of the constellations Aries the Ram and Taurus the Bull. A Full Moon can only lie in front of one or two of three constellations; the third is Cetus the Whale.
The overall duration of the 2022 November 8 Eclipse is predicted to be 5 hours and 54 minutes. The expectation for the duration of --- Totality: 1 hour, 25.7 minutes (one of the longest Total phases possible); both Partial Phases: 2 hours, 15 minutes; and both Penumbral Phases: 2 hours, 14 minutes.
Aristotle Discovers World is Round Due, in Part, to Lunar Eclipse / Eclipse of the Moon
Civilized society has known that the Earth is not flat, but is round, for about 2500 years. The famous Greek philosopher and academic, Aristotle who lived between 384 and 322 B.C., used a Lunar Eclipse / Eclipse of the Moon as one demonstration that the Earth is round.
This was documented in a book he published around 350 B.C. As he observed the Earth's shadow pass across the face of the Moon during a Lunar Eclipse / Eclipse of the Moon, he noticed that the shadow is curved, which is one of three indications he found that the Earth is round.
One of the other two indications were the concept that gravity required a common center for a planetary body such as Earth. He also noticed that different stars were seen from different locations on our planet, and some stars cannot be seen from certain locations.
Lunar Eclipse / Eclipse of the Moon Saves Christopher Columbus & Crew
On Christopher Columbus' fourth and last voyage to the New World (which he still believed was part of India or Asia) in 1502, he lost all four of his ships due to an epidemic of ship-worms eating holes in the wood planks of his vessels. He had to beach the last two ships on an island now known as Jamaica on 1503 June 25.
While waiting for a relief caravel to arrive from Hispaniola (island now occupied by the Dominican Republic and Haiti), the native Arawak Indians helped the castaways with food and provisions, in exchange for trinkets and other goods from the last two ships. However, after more than six months, the Arawaks got tired of helping the Spaniards, particularly after half the crew mutinied and robbed and murdered several Arawaks. With the Arawaks no longer providing food to the ships' crew, Columbus was now desperate.
From a German almanac carried on voyages by all navigators of this era, Columbus determined that a Total Lunar Eclipse / Total Eclipse of the Moon would be visible around moonrise in Jamaica on Thursday, 1504 February 29. Three days before the Eclipse, Columbus told the Arawak Chief that the Christian God was angry with the Arawaks for no longer providing the needs of Columbus' crew, and the God would make his anger known when the rising Full Moon is obliterated; the Moon would appear “inflamed with wrath”, illustrating what could happen to the Arawak people.
As Columbus had predicted, on February 29 the rising Moon appeared in an inflamed and bloody state. The terrified Arawaks immediately came running with provisions and requesting that Columbus intercede on their behalf with the Christian God. The Arawaks promised to cooperate with the ship-wrecked crew, so long as the Moon is returned to the sky in normal state.
Columbus retired to his ship cabin, to confer with the Christian God. He used an hour-glass to time the phases of the Eclipse. Just before the end of the Total Phase of the Eclipse, Columbus announced that the Christian God had pardoned the Arawaks, and the Moon would gradually return to normal, which, of course, did occur. From then on, the Arawaks did keep Columbus' crew well-supplied until the relief ship arrived on 1504 June 29.
In 1889, Mark Twain (a.k.a Samuel Clemens) used a similar ploy in his famous novel, A Connecticut Yankee in King Arthur's Court. To avoid being burned at the stake, main character Hank Morgan claimed the power to take away the Sun, at a time he knew a Total Solar Eclipse / Total Eclipse of the Sun would occur. Hank Morgan said he would return the Sun to normal, in return for his freedom and the position of “perpetual minister and executive to the king.”
However, Mark Twain did not consult an almanac, when writing the story. The date he used for the Eclipse, A.D. 528 June 21, was the first full day of Summer but not the date of any Eclipse. In fact, that date was three days after a Full Moon phase, when no Eclipse is possible.
Two Taurid Meteor Showers
Two Taurid Meteor Showers (South Taurid and North Taurid) may be slightly visible during this Eclipse. Although Lunar Eclipses / Eclipses of the Moon are not usually the best time to see Meteors (as a bright Moon often drowns-out the dimmer Meteors), some Meteors may still be visible, particularly during the time of greatest Eclipse.
The South Taurid Meteor Shower peaks on Saturday, 2022 November 5 at 1:00 p.m. EST /18:00 UTC. The peak of the North Taurid Meteor Shower comes on Saturday, 2022 November 12 at 1:00 p.m. EST /18:00 UTC.
Full Moon of November
The Full Moon of November, in the Northern Hemisphere, is generally known as the Beaver Moon. This was the time when Native Americans set-out beaver traps, before creeks and swamps froze-over, to ensure a good supply of warm furs and pelts for the coming Winter. Although beavers do not hibernate, by the following month the beavers would be in their lodges for the Winter, difficult for hunters to trap.
This beaver fur was its most usable at this time of year, both waterproof and warm. The furs also provided a special oil, used as a hair protector. The beaver was revered by the Americans Indians, spiritually.
The Beaver Moon occurs this year on 2022 November 8 at 6:02 a.m. EST / 11:02 UTC.
While most people consider the Full Moon as the Beaver Moon, the Native Americans actually considered the whole Moon cycle (all four Moon phases) as the Beaver Moon (i.e. the Beaver Month for the 28.5-day lunar cycle). Other researchers believe the Beaver Moon name came from the fact that beavers, themselves, are active building water dams, preparing for Winter.
This month's Full Moon sometimes is also referred to as the Frost or Frosty Moon. And, some Indian tribes referred to the November Full Moon as the Deer-Mating Moon or the Fur-Pelts Moon.
For years when the Harvest Moon occurs in October (when the October Full Moon date is closer to the Autumnal Equinox than the September Full Moon date, which occurs about one-third of the time), the November Full Moon is then also known as the Hunter's Moon. If the November Full Moon occurs before November 7, then it is a Hunter's Moon. However, this was not the case this year.
In the Southern Hemisphere, the Full Moon of November is known as the Corn Moon, Milk Moon, Flower Moon, and Hare Moon.
Daylight Saving Time Ends
Just before this Eclipse occurs, Daylight Saving Time (there is no letter “s” at the end of the word “Saving” in Daylight Saving Time) ends in the majority of the United States, which observe Daylight Saving Time from the second Sunday of March to the first Sunday of November each year. “Summer Time” ended in the United Kingdom and most of Europe the previous weekend, when America's Daylight Saving Time used to end before a change in U.S. Federal law effective beginning in 2007.
Mexico also changed their clocks from Daylight Saving Time to Standard Time last weekend, permanently! On October 26, the Mexican Senate approved a law that abolishes Daylight Saving Time over the entire country. However, northern regions of Mexico, along the American border, are permitted to continue observing Daylight Saving Time, to be consistent with the American time zone across the border. Andres Manuel Lopez Obrador, President of Mexico, called Standard Time, "God's time".
Daylight Saving Time ends at 2:00 a.m. Daylight Saving Time, which then becomes 1:00 a.m. Standard Time, on Sunday Morning, 2022 November 6. This is effective in all American states except in two states where Standard Time is observed year-round: Arizona (although tribal nations in Arizona do observe Daylight Saving Time) and Hawaii (which does not consider Daylight Saving Time necessary, due to the state's proximity to the Equator).
The American dates and times of Daylight Saving Time are also effective in most of Canada, except most of the province of Saskatchewan and the Yukon territory which stay on Standard Time all year. Some areas of the provinces of British Columbia and Quebec and Southampton Island (Kilvalliq Region of the territory of Nunavut) also remain on Standard Time year-round.
Mars Closest Approach to Earth & Opposition at End of Month & Beginning of December
The planet Mars will be at its closest approach to Earth, for the last two years and two months, on Wednesday, 2022 November 30 at 9:00 p.m. EST / December 1, 2:00 UTC. Mars will be at a Magnitude of -1.8 with the Martian disk appearing as large as 17.2 seconds-of-arc in diameter, just 4.5 light-minutes away (distance of 0.544 Astronomical Units).
Mars will be in Opposition (with the Earth lying directly between Mars and the Sun - Mars visible all-night-long, approximately local sunset to local sunrise) on Thursday, 2022 December 8 at 1:00 a.m. EST / 6:00 UTC. The Red Planet will appear fairly close to the December Full Moon (Full Moon on Wednesday, 2022 December 7 at 11:08 p.m. EST / December 8, 4:08 UTC).
In fact, the Moon will completely cover the planet Mars, in what astronomers call an Occultation, on Wednesday, 2022 December 7 at 11:00 p.m. EST / December 8 at 4:00 UTC. This Lunar Occultation should be visible, weather-permitting, in most of the United States (except Alaska), Canada, Greenland, northwestern portion of Mexico, Svalbard (archipelago part of Norway), much of Europe, western portion of Russia, and a portion of northern Africa. For other observers, Mars will be in Conjunction with the Full Moon (Mars 0.5 degree south of the Moon).
On Saturday, 2022 November 19, a $4.48 million exhibit on the planet Mars will open at Pittsburgh's Carnegie Science Center. On Saturday, 2022 October 15, a $2.7 million Moonshot Space Museum, regarding robotic missions to the Moon, opened in Pittsburgh.
