The Moon's hourly motion west to east through the constellation of Capricornus and the northern edge of the Earth's penumbral shadow

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.

Visibility

The eclipse was completely visible over Africa and Europe and South America. It was seen rising over eastern North America and setting over Asia.

Lunar year cycles (354 days)

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.

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 155.

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 took place on Sunday, November 9, 2003, the second of two total lunar eclipses in 2003, the first being on May 16, 2003. It is the first total lunar eclipse of 21st century which happened on a micromoon day. The Moon barely edged into total eclipse for 21 minutes and 58 seconds. With the Moon just 1.78% of its diameter into the Earth's umbral shadow, the Moon may have been quite bright, but even so, this should have been worth seeing. The partial eclipse lasted for 3 hours, 31 minutes and 25 seconds. Occurring only 1.4 days before apogee, the Moon's apparent diameter was 6.4% smaller than average.

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.

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">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 was also notable, because it occurred during a blue moon and was near perigee. The next eclipse on New Year's Eve and blue moon will occur on 31 December 2028.

A penumbral lunar eclipse took place on 24–25 May 2013, the second of three lunar eclipses in 2013. It was visually imperceptible due to the small entry into the penumbral shadow.

<span class="mw-page-title-main">April 2013 lunar eclipse</span> Partial lunar eclipse 25 April 2013

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">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 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

A penumbral lunar eclipse took place on 16 September 2016, the last of three lunar eclipses in 2016.

A penumbral lunar eclipse took place on Thursday, March 3, 1988, the first of two lunar eclipses in 1988, the second being on August 27, 1988. Earlier sources compute this as a 0.3% partial eclipse lasting under 14 minutes, and newest calculations list it as a penumbral eclipse that never enters the umbral shadow. 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, 53 minutes and 50.6 seconds in all, though for most of it, the eclipse was extremely difficult or impossible to see. The Moon was 2.2 days after apogee, making it 6.1% smaller than average.

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">July 2027 lunar eclipse</span>

A penumbral lunar eclipse will take place on 18 July 2027. The Moon will barely clip the edge of the Earth's penumbral shadow, and the eclipse will be impossible to see in practice. The event is listed as a miss by some sources.

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.
