The entire umbral phase was visible after sunset Saturday evening throughout the Pacific, New Zealand, Australia, the Philippines and Japan. The point where the Moon was directly overhead at maximum eclipse lay over the South Pacific Ocean, far to the southwest of Hawaii. The lunar eclipse seen over the Philippines on Saturday evening despite rainshowers and thick clouds, but it was clearly visible throughout the night sky.

Eclipses of 2010

Lunar year (354 days)

This eclipse is the one of five lunar eclipses in a short-lived series. The lunar year series repeats after 12 lunations or 354 days (Shifting back about 10 days in sequential years). Because of the date shift, the Earth's shadow will be about 11 degrees west in sequential events.

Metonic series (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.

A total solar eclipse occurred on March 29, 2006. 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. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. It was visible from a narrow corridor which traversed half the Earth. The magnitude, that is, the ratio between the apparent sizes of the Moon and that of the Sun, was 1.052, and it was part of Saros 139.

A total lunar eclipse occurred from 5:27 to 11:06 UTC on 21 December 2010, coinciding with the date of the Winter solstice in the Northern Hemisphere and Summer solstice in the Southern Hemisphere. It was visible in its entirety as a total lunar eclipse in North and South America, Iceland, Ireland, Britain and northern Scandinavia.

<span class="mw-page-title-main">June 2011 lunar eclipse</span> Central lunar eclipse

A total lunar eclipse took place on 15 June 2011. It was the first of two such eclipses in 2011. The second occurred on 10 December 2011. 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.

<span class="mw-page-title-main">December 2011 lunar eclipse</span> Total lunar eclipse of 10 December 2011

A total lunar eclipse took place on 10 December 2011. It was the second of two total lunar eclipses in 2011, the first having occurred on June 15. A lunar eclipse occurs when the moon is positioned just right in its orbit to pass through Earth's shadow.

<span class="mw-page-title-main">August 2009 lunar eclipse</span> Penumbral lunar eclipse 6 August 2009

A penumbral lunar eclipse took place on 6 August 2009, the third of four lunar eclipses in 2009. The moon's small entry into the Earth's penumbral shadow produced an extremely subtle dimming of the moon's southern edge, difficult to observe visually.

<span class="mw-page-title-main">December 2009 lunar eclipse</span>

A partial lunar eclipse was visible on 31 December 2009. It was the last and largest of four minor lunar eclipses in 2009. This lunar eclipse is also notable, because it occurred during a blue moon. The next eclipse on New Year's Eve and blue moon will occur on 31 December 2028.

<span class="mw-page-title-main">June 2012 lunar eclipse</span> Partial Lunar Eclipse on June 4 2012

A partial lunar eclipse took place on 4 June 2012. It was the first of two lunar eclipses occurring in 2012, the second eclipse set to happen on 28 November. The moon was about 37% covered by the Earth's northern umbral shadow at maximum eclipse.

<span class="mw-page-title-main">October 2014 lunar eclipse</span> Partial lunar eclipse of 8 October 2014

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.

<span class="mw-page-title-main">April 2015 lunar eclipse</span> Total lunar eclipse of 4 April 2015

A total lunar eclipse took place on 4 April 2015. It is the former of two total lunar eclipses in 2015, and the third in a tetrad. Other eclipses in the tetrad are those of 15 April 2014, 8 October 2014, and 28 September 2015.

<span class="mw-page-title-main">September 2015 lunar eclipse</span> Total lunar eclipse of 27 September 2015

A total lunar eclipse took place between 27 and 28 September 2015. It was seen on Sunday evening, 27 September, in the Americas; while in Europe, Africa, and the Middle East, it was seen in the early hours of Monday morning, 28 September. It was the latter of two total lunar eclipses in 2015, and the final in a tetrad. Other eclipses in the tetrad are those of 15 April 2014, 8 October 2014, and 4 April 2015.

<span class="mw-page-title-main">May 2040 lunar eclipse</span> 2040 astronomical phenomenon

A total lunar eclipse will take place on May 26, 2040. The northern limb of the moon will pass through the center of the Earth's shadow. This is the second central lunar eclipse of Saros series 131.

<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">May 2022 lunar eclipse</span> Total lunar eclipse of 15–16 May 2022

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 partial lunar eclipse took place on Saturday, August 27, 1988, the second of two lunar eclipses in 1988, the first being on March 3, 1988. The Earth's shadow on the moon was clearly visible in this eclipse, with 29.159% of the Moon in shadow; the partial eclipse lasted for 1 hour, 52 minutes and 59.7 seconds. The Moon was only 5 hours and 48 minutes before perigee, making it 6.3% larger than average

<span class="mw-page-title-main">November 2021 lunar eclipse</span> Partial lunar eclipse of 19 November 2021

A partial lunar eclipse occurred on 19 November 2021. The eclipse occurred towards a micromoon. This was the longest partial lunar eclipse since 18 February 1440, and the longest until 8 February, 2669; however, many eclipses, including the November 2022 lunar eclipse, have a longer period of umbral contact at next to 3 hours 40 minutes. It was often referred to as a "Beaver Blood Moon" although not technically fulfilling the criteria for a true blood moon (totality).

<span class="mw-page-title-main">April 1968 lunar eclipse</span> Total lunar eclipse April 13, 1968

A total lunar eclipse took place on Saturday, April 13, 1968, the first of two total eclipses in 1968, the second being on October 6, 1968.

<span class="mw-page-title-main">Solar eclipse of March 9, 2016</span> 21st-century total solar eclipse

A total solar eclipse took place at the Moon's descending node of the orbit on March 8–9, 2016. If viewed from east of the International Date Line, the eclipse took place on March 8 (Tuesday) and elsewhere on March 9 (Wednesday). A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's and the apparent path of the Sun and Moon intersect, blocking all direct sunlight and turning daylight into darkness; the sun appears to be black with a halo around it. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. The eclipse of March 8–9, 2016 had a magnitude of 1.0450 visible across an area of Pacific Ocean, which started in the Indian Ocean, and ended in the northern Pacific Ocean.

<span class="mw-page-title-main">Solar eclipse of January 15, 2010</span> 21st-century annular solar eclipse

An annular solar eclipse occurred at the Moon's ascending node of the orbit on January 15, 2010, with a magnitude of 0.91903. 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. It was the longest annular solar eclipse of the millennium, and the longest until December 23, 3043, with the length of maximum eclipse of 11 minutes, 7.8 seconds, and the longest duration of 11 minutes, 10.7 seconds. This is about 4 minutes longer than total solar eclipses could ever get.
