The Moon's hourly motion across the Earth's shadow in the constellation of Aquarius

A total lunar eclipse occurred on 28 August 2007, lasting just over 90 minutes. The Moon entered the Earth's penumbra at 7:53:40 UTC. The first partial phase began in earnest at 8:51:16 UTC when the Moon entered the Earth's umbra. It exited the penumbra at 13:20:57 UTC.

Contents

It was a relatively rare central eclipse where the Moon crossed the center of the Earth's shadow. It was the most recent central lunar eclipse of Saros series 128 as well as the "longest and deepest lunar eclipse to be seen in 7 years". In the total lunar eclipse of 16 July 2000 the moon passed within two arc minutes of the center of the Earth's shadow. In comparison, this still very deep eclipse was off-center by over 12 minutes of arc. [1] The next total lunar eclipse of a longer duration was on 15 June 2011.

The lunar eclipse was the second one in 2007. The first one occurred on 3 March 2007.

Viewing

Viewing from Oceania was favored for the eclipse, because at the moment of greatest eclipse (10:37:22 UTC), the Moon was at the zenith of French Polynesia. The Pacific regions of Canada and the continental United States (including all of Alaska) witnessed the whole event, along with most of eastern Australia, New Zealand and all the Pacific Island regions (except New Guinea), and the tip of the Chukchi Peninsula that includes the town of Uelen, Russia. The majority of the Americas observed an abbreviated eclipse, with moonset occurring at some time during the eclipse. Siberia, far eastern Russia, eastern South Asia, China, the rest of eastern and southeastern Asia, New Guinea, and the rest of Australia missed out on the beginning of the eclipse, because the eclipse occurred at or close to moonrise in those regions. [2]

Luzon (except Visayas and Mindanao) in the Philippines, particularly Metro Manila, missed the rare eclipse entirely, due to clouds in the area due to the rainy season, which saddened many eclipse watchers in the area, but the eclipse was sighted by other amateur astronomers in other parts of the country as the lunar eclipse seen in clear skies. The eclipse was also missed in New Guinea, especially Port Moresby because of clouds. Greenland, Europe (including western Russia), Africa, western Asia, western Central Asia, and western South Asia missed the eclipse completely.

Metonic cycle (19 years)

The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the Earth's shadow will be in nearly the same location relative to the background stars.

Saros series

Lunar saros series 128, repeating every 18 years and 11 days, has a total of 71 lunar eclipse events including 57 umbral eclipses (42 partial lunar eclipses and 15 total lunar eclipses). Solar Saros 135 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Lunar Saros 128 contains 15 total lunar eclipses between 1845 and 2097 (in years 1845, 1863, 1881, 1899, 1917, 1935, 1953, 1971, 1989, 2007, 2025, 2043, 2061, 2079 and 2097). Solar Saros 135 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros). [4] This lunar eclipse is related to two annular solar eclipses of Solar Saros 135.

A total lunar eclipse took place on Wednesday 8 October 2014. It is the second of two total lunar eclipses in 2014, and the second in a tetrad. Other eclipses in the tetrad are those of 15 April 2014, 4 April 2015, and 28 September 2015. Occurring only 2.1 days after perigee, the Moon's apparent diameter was larger, 1960.6 arcseconds.

A total lunar eclipse occurred on 15–16 May 2022, the first of two total lunar eclipses in 2022. The event occurred near lunar perigee; as a result, this event was referred to some in media coverage as a "super flower blood moon" and elsewhere as a "super blood moon", a supermoon that coincides with a total lunar eclipse. This was the longest total lunar eclipse visible from nearly all of North America since August 17, 1989 until the next eclipse on November 8.

<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 Friday, August 6, 1971, the second of two total lunar eclipses in 1971. A dramatic total eclipse lasting 1 hour, 39 minutes and 24.8 seconds 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, 35 minutes and 31.9 seconds in total. Occurring only 2.2 days before perigee, the Moon's apparent diameter was 3.6% larger than average and the moon passed through the center of the Earth's shadow.

A total lunar eclipse took place on Thursday, April 24, 1986, the first of two total lunar eclipses in 1986, the second being on October 17, 1986. The Moon was plunged into darkness for 1 hour, 3 minutes and 34.8 seconds, in a deep total eclipse which saw the Moon 20.217% 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, 18 minutes and 46.8 seconds in total. The Moon was just 1.2 days before perigee, making it 5.3% larger than average.

<span class="mw-page-title-main">September 2025 lunar eclipse</span> Total lunar eclipse of September 2025.

A total lunar eclipse will take place on 7-8 September 2025. The Moon will barely miss the center of the Earth's shadow. It will be the second of two total lunar eclipses. Occurring roughly 3 days before perigee, the Moon will appear larger than usual.

<span class="mw-page-title-main">June 2076 lunar eclipse</span> Central lunar eclipse

A total lunar eclipse will take place on June 17, 2076. The moon will pass through the center of the Earth's shadow. While the visual effect of a total eclipse is variable, the Moon may be stained a deep orange or red color at maximum eclipse. With a gamma value of only −0.0452 and an umbral eclipse magnitude of 1.7943, this is the second greatest eclipse in Saros series 131 as well as the largest and darkest lunar eclipse between June 26, 2029 and June 28, 2094. Overall, it will be the third largest and darkest lunar eclipse of the 21st century. While it will have similar values to the lunar eclipse of July 16, 2000, totality will not last over 106 minutes due to the moon's relatively large apparent size as seen from Earth and greater speed in its elliptical orbit. Totality's expected to last 100 minutes 34 seconds from 9:11:39 to 10:52:15 with the greatest point at 10:01:57 UTC.
