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

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 was also notable, because it occurred during a blue moon (a second full moon in December) and was near perigee (making it a supermoon). The next eclipse on New Year's Eve and blue moon will occur on 31 December 2028.

Contents

Only a small portion of the Moon entered the Earth's umbral shadow, but there was a distinct darkening visible over the Moon's southern surface at greatest eclipse.

It was visible from all of Africa, Europe, Asia, Middle East and Australia. In the Philippines, the lunar eclipse was started last 1 January 2010, when it was very visible at mid-dawn until before sunrise.

Eclipses of 2009

Lunar year (354 days)

This eclipse is the one of four 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.

Saros series

It was part of Saros series 115.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros). [1] This lunar eclipse is related to two partial solar eclipses of Solar Saros 122.

A partial lunar eclipse took place on 16 August 2008, the second of two lunar eclipses in 2008, with the first being a total eclipse on 20 February 2008. The next lunar eclipse was a penumbral eclipse occurring on 9 February 2009, while the next total lunar eclipse occurred on 21 December 2010.

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">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">July 2009 lunar eclipse</span> Penumbral lunar eclipse 20 July 2009

A penumbral lunar eclipse took place on 7 July 2009, the second of four lunar eclipses in 2009. This eclipse entered only the southernmost tip of the penumbral shadow and thus was predicted to be very difficult to observe visually. This lunar eclipse was the predecessor of the solar eclipse of 22 July 2009.

<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.

A partial lunar eclipse took place on 25 April 2013, the first of three lunar eclipses in 2013. Only a tiny sliver (1.48%) of the Moon was covered by the Earth's umbral shadow at maximum eclipse, but the entire northern half of the Moon was darkened from being inside the penumbral shadow. This was one of the shortest partial eclipses of the Moon for the 21st century, lasting 27 minutes. This was the last of 58 umbral lunar eclipses of Lunar Saros 112.

<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.

A penumbral lunar eclipse took place on 23 March 2016, the first of three lunar eclipses in 2016. The Moon was just 2.1 days before apogee, making it very small, so this was a "Micromoon" penumbral lunar eclipse.

<span class="mw-page-title-main">September 2016 lunar eclipse</span> Penumbral lunar eclipse 16 September 2016

<span class="mw-page-title-main">August 2017 lunar eclipse</span> Partial lunar eclipse of August 7, 2017

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.

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">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).

A penumbral lunar eclipse took place on 30 November 2020. A penumbral lunar eclipse occurs at full moon when the Moon passes through Earth's penumbral shadow.

<span class="mw-page-title-main">April 1967 lunar eclipse</span> Total lunar eclipse April 24, 1967

A total lunar eclipse took place on Monday, April 24, 1967, the first of two total lunar eclipses in 1967, the second being on October 18, 1967.
