A partial lunar eclipse occurred on Tuesday, July 25, 1972 and Wednesday, July 26, 1972, the second of two lunar eclipses in 1972 with an umbral eclipse magnitude of 0.54271. A partial lunar eclipse occurs when the Earth moves between the Sun and Moon but the three celestial bodies do not form a straight line in space. When that happens, a small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow, called the umbra. The rest of the Moon is covered by the outer part of the Earth's shadow called the penumbra. [1] The moon's apparent diameter was 3.2 arcseconds smaller than the January 30, 1972 lunar eclipse.

A partial lunar eclipse took place at the Moon's descending node on the evening of 7 August and the morning pre-dawn on 8 August 2017, the second of two lunar eclipses in 2017. The Moon was only slightly covered by the Earth's umbral shadow at maximum eclipse. The Moon's apparent diameter was smaller because the eclipse occurred only 5 days after apogee.

<span class="mw-page-title-main">November 2022 lunar eclipse</span> Total lunar eclipse on 8 November 2022

A total lunar eclipse occurred on Tuesday, 8 November 2022. The southern limb of the Moon passed through the center of the Earth's shadow. It surpassed the previous eclipse as the longest total lunar eclipse visible from nearly all of North America since 17 August 1989, and until 26 June 2029. Occurring only 5.8 days before apogee, the Moon's apparent diameter was smaller. The next total lunar eclipse will take place on 14 March 2025. A lunar occultation of Uranus happened during the eclipse. It was the first total lunar eclipse on Election Day in US history. This event was referred in media coverage as a "beaver blood moon".

<span class="mw-page-title-main">July 2018 lunar eclipse</span> Central lunar eclipse on 27 July 2018

A total lunar eclipse occurred at the Moon's descending node on 27 July 2018. The Moon passed through the center of Earth's shadow in what was the first central lunar eclipse since 15 June 2011. It was also the second total lunar eclipse in 2018, after the one on 31 January. It was the longest total lunar eclipse of the 21st century, but not the longest in the 3rd millennium. The longest total lunar eclipse of the 3rd millennium will occur on May 12, 2264, lasting 106 minutes and 13.2 seconds, which will be the longest total lunar eclipse since 2000, and the longest one until 3107.

A total lunar eclipse took place on Tuesday, July 6, 1982, the second of three total lunar eclipses in 1982, and the only one that was in the descending node. A dramatic total eclipse lasting 1 hour and 46 minutes plunged the full Moon into deep darkness, as it passed right through the centre of the Earth's umbral shadow. While the visual effect of a total eclipse is variable, the Moon may have been stained a deep orange or red colour at maximum eclipse. This was a great spectacle for everyone who saw it. The partial eclipse lasted for 3 hours and 56 minutes in total.

A total lunar eclipse took place on Saturday, May 24 and Sunday, May 25, 1975, the first of two total lunar eclipses in 1975. The Moon was plunged into darkness for 1 hour and 28 minutes in a deep total eclipse which saw the Moon 43% of its diameter inside the Earth's umbral shadow. The visual effect of an eclipse depends on the state of the Earth's atmosphere, but the Moon may have been stained a deep red colour. The partial eclipse lasted for 3 hours and 35 minutes in total. Occurring only 4.4 days after perigee, the Moon's apparent diameter was 0.7% larger than average. The moon was 377,010 km from the Earth at greatest eclipse.

A total lunar eclipse took place at the Moon's descending node of the orbit on Wednesday, February 10, 1971, the first of two total lunar eclipses in 1971. It had an umbral magnitude of 1.30819. The Moon passed through the center of the Earth's shadow. The Moon was plunged into darkness for 1 hour, 22 minutes and 11.4 seconds, in a deep total eclipse which saw the Moon 30.819% of its diameter inside the Earth's umbral shadow. The visual effect of this depends on the state of the Earth's atmosphere, but the Moon may have been stained a deep red colour. The partial eclipse lasted for 3 hours, 44 minutes and 42.9 seconds and in total. Occurring only 2.7 days before apogee, the Moon's apparent diameter was 5.9% smaller than average.

A partial lunar eclipse took place on Saturday, June 25, 1983, the first of two lunar eclipses in 1983 with an umbral eclipse magnitude of 0.33479. A partial lunar eclipse happens when the Earth moves between the Sun and the Full Moon, but they are not precisely aligned. Only part of the Moon's visible surface moves into the dark part of the Earth's shadow. A partial lunar eclipse occurs when the Earth moves between the Sun and Moon but the three celestial bodies do not form a straight line in space. When that happens, a small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow, called the umbra. The rest of the Moon is covered by the outer part of the Earth's shadow called the penumbra. The Earth's shadow on the moon was clearly visible in this eclipse, with 33% of the Moon in shadow; the partial eclipse lasted for 2 hours and 15 minutes.

A penumbral lunar eclipse took place on Tuesday, January 20, 1981, the first of two lunar eclipses in 1981. In a rare total penumbral eclipse, the entire Moon was partially shaded by the Earth, and the shading across the Moon should have been quite visible at maximum eclipse. The penumbral phase lasted for 4 hours and 24 minutes in all, though for most of it, the eclipse was extremely difficult or impossible to see. The moon's apparent diameter was larger because the eclipse occurred 5.2 days after perigee.

<span class="mw-page-title-main">January 2018 lunar eclipse</span> Total lunar eclipse of January 31, 2018

A total lunar eclipse occurred on 31 January 2018. The Moon was near its perigee on 30 January and as such may be described as a "supermoon", when the Moon's distance from the Earth is less than 360,000 km. The previous supermoon lunar eclipse was in September 2015.

A penumbral lunar eclipse took place on Tuesday, September 27, 1977, the second of two lunar eclipses in 1977. At maximum eclipse, 90.076% of the Moon's disc was partially shaded by the Earth, which caused a slight shadow gradient across its disc; this subtle effect may have been visible to careful observers. No part of the Moon was in complete shadow. The eclipse lasted 4 hours, 17 minutes and 35.5 seconds overall. Occurring 6.2 days before apogee, the Moon's apparent diameter was 2.2% smaller than average.

A partial lunar eclipse took place on Tuesday, March 13, 1979, the first of two lunar eclipses in 1979. The Moon was strikingly shadowed in this deep partial eclipse which lasted 3 hours, 17 minutes and 40.6 seconds, with 85.377% of the Moon in darkness at maximum.

A total lunar eclipse took place on Tuesday, November 18, 1975, the second of two total lunar eclipses in 1975. A shallow total eclipse saw the Moon in relative darkness for 40 minutes and 11.1 seconds. The Moon was 6.421% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 29 minutes and 2.1 seconds in total. Occurring only 4.9 days after apogee, the Moon's apparent diameter was 4% smaller than average.

A partial lunar eclipse took place on Thursday, May 13, 1976, the first of two lunar eclipses in 1976, the second being a penumbral lunar eclipse on November 6, 1976. At maximum eclipse, a small bite out of the Moon should have been visible. The eclipse lasted for 1 hour, 15 minutes and 23.8 seconds, with just 12.17% of the Moon in shadow at maximum. Occurring only 1.1 days after perigee, the Moon's apparent diameter 5.4% larger than average.

A total lunar eclipse took place on Sunday, January 30, 1972, the first of two lunar eclipses in 1972. The moon entered the Earth's penumbral shadow at 30 January 1972 08:03:12.5 UTC and exited at 30 January 1972 13:43:37.9 UTC. The moon entered the Earth's umbral shadow at 30 January 1972 09:11:38.4 UTC and exited at 30 January 1972 12:35:03.1 UTC. Totality lasted 34 minutes, 47.7 seconds, between 10:35:57.4 UTC and 11:10:45.1 UTC. The moon was 6.6 days before apogee, making it 1.6% smaller than average, only 0.2% larger than the July 1972's lunar eclipse.

<span class="mw-page-title-main">July 1963 lunar eclipse</span> Partial lunar eclipse July 6, 1963

A partial lunar eclipse took place on Saturday, July 6, 1963 with an umbral eclipse magnitude of 0.70602. The Moon was strikingly shadowed in this deep partial eclipse which lasted 3 hours exactly, with 71% of the Moon in darkness at maximum. A partial lunar eclipse occurs when the Earth moves between the Sun and Moon but the three celestial bodies do not form a straight line in space. When that happens, a small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow, called the umbra. The rest of the Moon is covered by the outer part of the Earth's shadow called the penumbra. It was the second of three lunar eclipses in 1963, the first was a penumbral lunar eclipse on January 9, 1963 and the third and last was on December 30, 1963.

<span class="mw-page-title-main">November 1955 lunar eclipse</span> Partial lunar eclipse November 29, 1955

A partial lunar eclipse took place on Tuesday, November 29, 1955 with an umbral eclipse magnitude of 0.11899. A partial lunar eclipse happens when the Earth moves between the Sun and the Full Moon, but they are not precisely aligned. Only part of the Moon's visible surface moves into the dark part of the Earth's shadow. A partial lunar eclipse occurs when the Earth moves between the Sun and Moon but the three celestial bodies do not form a straight line in space. When that happens, a small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow, called the umbra. The rest of the Moon is covered by the outer part of the Earth's shadow called the penumbra. It was the second of two lunar eclipses in 1955, first being the penumbral lunar eclipse on June 5.

A total lunar eclipse took place at the Moon's descending node of the orbit on Tuesday, May 24, 1910 with an umbral eclipse magnitude of 1.09503. A total lunar eclipse takes place when the Earth comes between the Sun and the Moon and its shadow covers the Moon. Eclipse watchers can see the Moon turn red when the eclipse reaches totality. Total eclipses of the Moon happen at Full Moon when the Sun, Earth, and Moon are aligned to form a line. The astronomical term for this type of alignment is syzygy, which comes from the Greek word for being paired together. The Moon does not have its own light but shines because its surface reflects the Sun's rays. During a total lunar eclipse, the Earth comes between the Sun and the Moon and blocks any direct sunlight from reaching the Moon. The Sun casts the Earth's shadow on the Moon's surface. A shallow total eclipse saw the Moon in relative darkness for 49 minutes and 29.5 seconds. The Moon was 9.503% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 35 minutes and 22.9 seconds in total.

<span class="mw-page-title-main">Solar eclipse of February 4, 1981</span> 20th-century annular solar eclipse

An annular solar eclipse occurred at the Moon's descending node of the orbit on February 4–5, 1981. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. This annular solar eclipse was large because the Moon covered 99.4% of the Sun, with a path width of only 25 km . It was visible in Australia, crossing over Tasmania and southern Stewart Island of New Zealand near sunrise on February 5 (Thursday), and ended at sunset over western South America on February 4 (Wednesday). Occurring only 4 days before perigee, the moon's apparent diameter was larger.
