This lunar eclipse grazes the southern edge of the Earth's penumbral shadow occurs at the ascending node of the Moon's orbit, in the constellation of Sagittarius

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. [1] This lunar eclipse was the predecessor of the solar eclipse of 22 July 2009.

Lunar year (354 days)

This eclipse is 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.

This eclipse is a member of Saros series 110. The previous event occurred on 27 June 1991. The next event is on 18 July 2027 which will end the 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). [2] This lunar eclipse is related to two partial solar eclipses of Solar Saros 117.

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 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 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.

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">July 2047 lunar eclipse</span> Central lunar eclipse

A total lunar eclipse will take place on July 7, 2047. It will last 1 hour 40 minutes and 49 seconds and will plunge the full Moon into deep darkness, as it passes right through the centre of the Earth's umbral shadow. While the visual effect of a total eclipse is variable, the Moon may be stained a deep orange or red colour at maximum eclipse. This will be a great spectacle for everyone who sees it. The partial eclipse will last for 3 hours and 39 minutes in total.

<span class="mw-page-title-main">June 1991 lunar eclipse</span> Penumbral lunar eclipse June 27, 1991

A penumbral lunar eclipse took place on Thursday, June 27, 1991, the second of four lunar eclipses in 1991. The moon entered the Earth's penumbra for about 3 hours, and was difficult to see. This lunar eclipse is the predecessor of the Solar eclipse of July 11, 1991.

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.
