The Supermoon lunar eclipse of 2015 was the first such combination since 1982, and was the largest diameter Moon to be seen in lunar eclipse in more than three decades. 2018 had one, and so will 2019 on January 20/21.Jimmy Baikovicius from Uruguay

When the Sun, Earth, and Moon line up just properly, the shadow cast by our planet can fall onto the Moon. If the alignment is perfect, the result will be a total lunar eclipse, where the entirety of the Moon enters the darkest part of Earth’s shadow. During this time, anyplace on Earth’s surface that experiences night will be treated to the spectacular show of a completely red, dim Moon.

Total lunar eclipses are relatively common; we get about one per year, on average. But something special is happening on the night of January 20th/21st: the entirety of the North and South American continents will get to experience the full show of the eclipse. This includes the penumbral, partial, and total stages from everywhere in the Americas. It’s the first time this will happen since the year 2000, and the last time it will occur until 2058.

The area shown in red, here, will get to observe the total lunar eclipse of January 2019 from Earth. This includes everyone in North and South America with clear skies.TimeAndDate.com

The way lunar eclipses occur is straightforward, from a scientific standpoint. As the Earth orbits the Sun, there’s always a shadow-cone trailing the Earth: a region where direct sunlight cannot fall since it’s obscured by the presence of our planet. With a diameter of some 12,700 km (8,600 miles) orbiting at a distance of 150 million km (93 million miles) from the Sun, Earth’s shadow extends for approximately 1.4 million kilometers.

The Moon, on the other hand, is just 380,000 kilometers away on average, with a diameter of ~3,500 km (2,200 miles). On January 20/21, the Moon will be at perigee: its closest point to Earth. The size of Earth’s shadow, relative to where the Moon will be, is approximately three times as large as the Moon at this time.

By digitally stitching together a series of images during the July 27th, 2018 lunar eclipse, Tom Harradine was able to demonstrate the relative size of Earth’s shadow on the Moon to the size of the apogee Moon itself. The January 20/21, 2019 eclipse will occur with the moon at perigee, resulting in a larger-sized apparent shadow.Tom Harradine, via Facebook, with permission

The Moon orbits the Earth and the Earth orbits the Sun, but they don’t orbit in exactly the same plane as one another. The Moon-Earth plane is tilted with respect to the Sun-Earth plane by 5.2°, meaning that there are only two times during every month where the Moon is located in the same plane as Earth’s shadow.

Since the Moon is about half a degree (0.5°) in diameter, most of the time a full Moon — the one alignment where the Moon might fall into Earth’s shadow — will be located either above or below the Earth-Sun plane. It’s only once or twice a year, typically, that a lunar eclipse becomes possible.

In order for an eclipse to occur, the nodes of the Moon’s orbit must line up with the Earth-Sun plane during a new or full moon. Having this align with the Moon at either perigee or apogee and with the Earth close to either perihelion or aphelion is a very rare occurrence indeed.James Schombert / University of Oregon

Most times, the Moon’s alignment isn’t perfect with respect to the Earth-Sun plane, and we only get either a penumbral eclipse or a partial eclipse.

A penumbral eclipse, for most skywatchers, isn’t even worth seeing. From certain points on the lunar surface, if you were looking at the Sun, you’d see that a portion of the Sun’s disk was obscured by the Earth. The locations that see more of that obscuration will appear slightly darker, but still illuminated by sunlight. During the penumbral phase of any eclipse — which precedes and follows any partial phases — “limb darkening” of portions of the Moon are the only discernable feature.

When passing through a large amount of atmosphere, the bluer wavelengths of light are mostly scattered away, while the red light can make it through and land on the lunar surface during a total eclipse, which is why the Moon is visible, but red and dim, during a total lunar eclipse. The locations of the total and penumbral phases are shown here, while the partial phases occur when the Moon is partially in and partially out of the umbral shadow.NASA

Partial eclipses are a little more exciting; that’s when the Earth’s umbral shadow (the dark part) falls onto the lunar surface. If you were located on the Moon, you’d see the entire Sun eclipsed by the intervening Earth from the dark locations. Even if the alignment is imperfect between the Earth, Moon, and Sun, partial eclipses can still occur.

But when you have the right alignment, a penumbral eclipse leads to a partial eclipse, and then the partial eclipse becomes a total eclipse. Once the entire Moon is located inside the Earth’s shadow, the real fun begins. The total phase of a lunar eclipse is one of the most spectacular recurring sights to skywatchers anywhere on the night side of Earth.

During most total lunar eclipses, a partial eclipse is followed by a dark red color appearing to overtake the Moon from one side, with one limb always remaining brighter and whiter than the other. The partial phases, combined with the apparent angular size of the Moon, enable us to determine the relative sizes of the Earth and Moon, the distance between them, and will eventually lead us to the Earth-Sun distance and the stars.KAZUHIRO NOGI/AFP/Getty Images

The views are spectacular. The full Moon is normally the brightest object in the night sky, but during totality, it might be outshone by the brightest stars and planets. Venus, Jupiter, and even Mars or Saturn often outshine an eclipsed Moon, as can the bright stars Sirius, Canopus, Alpha Centauri and Arcturus.

Stars near the Moon are normally washed out by the large amount of reflected light, but during a total eclipse, the sky becomes almost as pristine as it would on a moonless night. The Moon itself is still visible, as the sunlight that filters through Earth’s atmosphere falls on the lunar surface. From the Moon, you would see only a red “ring” around Earth that illuminated you, as the bluer wavelengths get scattered away by Earth’s atmosphere. The same effects that turn our sky blue during the day turn the Moon red during a total eclipse!

In April of 2014, a total lunar eclipse occurred close to Mars (at upper right) in the sky. On July 27, 2018, Mars dramatically outshone the fully eclipsed Moon at the maximum point of totality. Some of the planets visible in the sky during the January 20/21, 2019 eclipse, such as Venus in the late night/early morning skies, will outshine the eclipsed Moon as well.Sodai Gomi / flickr

You might think that it’s special to have this eclipse be a “Supermoon” lunar eclipse, but in reality, that’s not particularly special. As the Moon orbits the Earth, it not only goes through its phases, from new to full to new again, but it moves in an ellipse around the Earth. When it’s farthest from Earth, at apogee, it can reach distances as great as 406,700 km from our center; at perigee, its closest approach, it can get as close as only 356,400 km away. When a full Moon phase and a perigee (or near-perigee) place in its orbit coincide, we call that a Supermoon.

The word Supermoon came into the public lexicon in 2011, where three Supermoons in a row graced the night sky. Shown here is the central one from that event, observed over Munich, Germany. The Moon is discolored because of the light filtering through Earth’s atmosphere, not because of an eclipse (in this photo).Kai Schreiber of flickr

Typically, a full Moon that’s closer than 359,000 km (or, alternatively, 360,000 km) will be known as a Supermoon, and we usually get around 3 of them consecutively due to the intricacies of the orbits of the Sun, Earth and Moon. January, Februrary, and March will all have Supermoons in 2019.

Remarkably, binoculars or a telescope will allow you to see incredible features of the Moon with no additional filters. Normally, viewing the Moon through binoculars or a telescope is very harsh on the eyes, and impossible without a special lunar filter due to the Moon’s overwhelming brightness.

By looking at the curvature of the Earth’s shadow that falls on the Moon, we can reconstruct the relative size of the Moon versus the Earth’s shadow-cone, allowing us to geometrically reconstruct the Earth-Moon distance. During the total phase of a lunar eclipse, many features can be clearly seen on the Moon’s surface without the need for a special lunar filter.Fred Espenak / MrEclipse.com

But viewing the Moon during totality, or the partially-eclipsed portion of it before-or-after totality, gives a special treat. Sights you should look for include:

  • crater rays emanating from the large, prominent craters Tycho, Copernicus, and Aristarchus,
  • all of the lunar maria: the dark features first identified in the earliest days of the telescope,
  • the feature changes during the partial phases as Earth’s shadow advances and retreats, including crater wall changes, and
  • a narrow, blue band at the edge of the shadow, caused by the effects of Earth’s atmosphere. (This is particularly good through a telescope!)

The dark lunar lowlands (known as maria), crater rays, and even craters themselves can be seen with binoculars or a low-power telescope directly, with no filter, during the maximal stages of a total lunar eclipse.Nick Ut/Getty Images

But what makes this eclipse so special is when it occurs relative to the Earth’s rotation. When the first stage of the eclipse begins, Europe and Africa will be nearing sunrise, but all of North and South America (as well as parts of Russia) will be full-on into the start of night.

As the Earth continues to turn and the Moon moves through the Earth’s shadow, the eclipse will go from penumbral to partial to total, with totality lasting for over an hour, before becoming a partial and then penumbral eclipse again.

Small portions of northern Europe and northern Asia will experience the entirety of the eclipse, but all of North and South America will get to view the entire thing. This marks the first Pan-American eclipse of the 21st century!

The Moon’s orbit isn’t a perfect circle, but an ellipse. When perigee coincides (or nearly coincides) with fullness, we achieve a Supermoon.Brian Koberlein

Supermoon lunar eclipses that are also total eclipses typically occur in clusters where you’ll get one for a few consecutive years, and then there’s a drought that typically lasts around a decade. Eclipses that cover all of North and South America are exceedingly rare, occurring just a few times per century. This January 20th/21st, everything will line up perfectly for skywatchers living in Earth’s western hemisphere.

The next time we’ll have a total lunar eclipse with the same visibility from Earth won’t be until November 30th, 2058: nearly 40 years from now. Skywatchers from the Bering Strait, Iceland, Ireland and the United Kingdom will be able to join everyone living in the Americas in viewing this spectacular sight. This is also the last total lunar eclipse Earth will experience for more than two years, so make sure you take advantage of your chance if the weather allows. Clear skies to you all!

However seeing the Moon throughout totality, or the partially-eclipsed part of it before-or-after totality, offers an unique reward. Sights you must search for consist of:

    .

  • crater rays originating from the big, popular craters Tycho, Copernicus, and Aristarchus,
  • all of the lunar maria: the dark functions initially recognized in the earliest days of the telescope,
  • the function modifications throughout the partial stages as Earth’s shadow advances and retreats, consisting of crater wall modifications, and
  • a narrow, blue band at the edge of the shadow, triggered by the results of Earth’s environment. (This is especially excellent through a telescope!)

However what makes this eclipse so unique is when it happens relative to the Earth’s rotation. When the very first phase of the eclipse starts, Europe and Africa will be nearing daybreak, however all of North and South America (in addition to parts of Russia) will be full-on into the start of night.

As the Earth continues to turn and the Moon moves through the Earth’s shadow, the eclipse will go from penumbral to partial to overall, with totality lasting for over an hour, prior to ending up being a partial and after that penumbral eclipse once again.

Little parts of northern Europe and northern Asia will experience the totality of the eclipse, however all of North and South America will get to see the whole thing. This marks the very first Pan-American eclipse of the 21 st century!

Supermoon lunar eclipses that are likewise overall eclipses usually take place in clusters where you’ll get one for a couple of successive years, and after that there’s a dry spell that usually lasts around a years. Eclipses that cover all of North and South America are extremely unusual, taking place simply a couple of times per century. This January 20 th/ 21 st, whatever will line up completely for skywatchers residing in Earth’s western hemisphere.

The next time we’ll have an overall lunar eclipse with the very same exposure from Earth will not be up until November 30 th, 2058 : almost 40 years from now. Skywatchers from the Bering Strait, Iceland, Ireland and the UK will have the ability to sign up with everybody living in the Americas in seeing this amazing sight. This is likewise the last overall lunar eclipse Earth will experience for more than 2 years, so make certain you benefit from your possibility if the weather condition enables. Clear skies to you all!
