Metonic series

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.

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 117.

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.

November 2003 lunar eclipse Total lunar eclipse November 9, 2003

A total lunar eclipse took place on 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 in a micromoon day.

April 2005 lunar eclipse Penumbral lunar eclipse April 24, 2005

A penumbral lunar eclipse took place on April 24, 2005, the first of two lunar eclipses in 2005. At maximum eclipse, 87% of the Moon's disc was partially shaded by the Earth, which caused a slight shadow gradient across its disc; this subtle effect may have been visible to careful observers. No part of the Moon was in complete shadow. The eclipse lasted 4 hours and 6 minutes overall, and was visible from east Asia, Australia, and the Americas.

A penumbral lunar eclipse took place on 14 March 2006, the first of two lunar eclipses in 2006.

Solar eclipse of July 11, 1991 20th-century total solar eclipse

A total solar eclipse occurred on July 11, 1991. 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. Totality began over the Pacific Ocean and Hawaii moving across Mexico, down through Central America and across South America ending over Brazil. It lasted for 6 minutes and 53.08 seconds at the point of maximum eclipse. There will not be a longer total eclipse until June 13, 2132. This was the largest total solar eclipse of Solar Saros series 136, because eclipse magnitude was 1.07997.

October 1985 lunar eclipse Total lunar eclipse October 28, 1985

A total lunar eclipse took place on October 28, 1985, the second of two total lunar eclipses in 1985, the first being on May 4, 1985.

August 1988 lunar eclipse Partial lunar eclipse August 27, 1988

A partial lunar eclipse took place on December 21, 1991, the last of four lunar eclipses in 1991. The moon grazed the northern edge of the umbral shadow.

March 1988 lunar eclipse Penumbral lunar eclipse March 3, 1988

A penumbral lunar eclipse took place on March 3, 1988, the first of two lunar eclipses in 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.

July 1991 lunar eclipse Penumbral lunar eclipse July 26, 1991

A penumbral lunar eclipse took place on Friday, July 26, 1991, the third of four lunar eclipses in 1991. This was the 2nd member of Lunar Saros 148. The previous event was on 15 July 1973, and the 1st eclipse of the series. The next event will be on 6 August 2009.

November 1984 lunar eclipse Penumbral lunar eclipse November 8, 1984

A penumbral lunar eclipse took place on November 8, 1984. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 90% of the Moon's disc was partially shaded by the Earth, which caused a gentle shadow gradient across its disc at maximum; the eclipse as a whole lasted 4 hours and 28 minutes.

May 1984 lunar eclipse Penumbral lunar eclipse May 15, 1984

A penumbral lunar eclipse took place on May 15, 1984. This was a deep penumbral eclipse, with the southern limb of the Moon close to the Earth's shadow.

A penumbral lunar eclipse took place on January 20, 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.

A penumbral lunar eclipse will take place on 5 May 2023.

August 2026 lunar eclipse

A partial lunar eclipse will take place on August 28, 2026. The moon will be almost be inside the umbra, but not quite be contained within the umbral shadow at greatest eclipse.

February 2027 lunar eclipse

A penumbral lunar eclipse will take place on 20–21 February 2027.

May 2031 lunar eclipse Penumbral

A penumbral lunar eclipse will take place on May 7, 2031.

October 1967 lunar eclipse Total lunar eclipse October 18, 1967

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

March 2044 lunar eclipse

A total lunar eclipse will take place on March 13, 2044.

Solar eclipse of January 15, 1991 20th-century annular solar eclipse

An annular solar eclipse occurred on January 15–16, 1991. 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. Annularity was visible in southwestern Western Australia, Tasmania, New Zealand and French Polynesia. It was visible over Australia as a partial solar eclipse at sunrise on January 16.
