**Jean Meeus** (born 12 December 1928) is a Belgian meteorologist and amateur astronomer specializing in celestial mechanics, spherical astronomy, and mathematical astronomy.^{ [1] }^{ [2] }

Meeus studied mathematics at the University of Leuven in Belgium, where he received the Degree of Licentiate in 1953. From then until his retirement in 1993, he was a meteorologist at Brussels Airport.^{ [2] }

In 1986, he won the Amateur Achievement Award of the Astronomical Society of the Pacific.^{ [3] } The main belt asteroid 2213 Meeus was named after him by the International Astronomical Union in 1981 for his contributions to the field.^{ [1] }^{ [2] }

The **saros** is a period of exactly 223 synodic months, approximately 6585.3211 days, or 18 years, 10, 11, or 12 days, and 8 hours, that can be used to predict eclipses of the Sun and Moon. One saros period after an eclipse, the Sun, Earth, and Moon return to approximately the same relative geometry, a near straight line, and a nearly identical eclipse will occur, in what is referred to as an eclipse cycle. A **sar** is one half of a saros.

**Fred Espenak** is a retired emeritus American astrophysicist. He worked at the Goddard Space Flight Center. He is best known for his work on eclipse predictions.

A **total lunar eclipse** took place on 16 July 2000, the second of two total lunar eclipses in 2000.

A **penumbral lunar eclipse** took place on September 6, 1998, the last of three lunar eclipses in 1998.

A **total lunar eclipse** took place on July 6, 1982.

A **total lunar eclipse** took place on December 30, 1982. A shallow total eclipse saw the Moon in relative darkness for 1 hour exactly. The Moon was 18% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours and 16 minutes in total. This was a supermoon since perigee was on the same day. It was also a blue moon, the second full moon of December for the eastern hemisphere where the previous full moon was on December 1. Since total lunar eclipses are also known as blood moons, this combination is known as a *super blue blood moon*.

A **partial lunar eclipse** took place on June 25, 1983. The Earth's shadow on the moon was clearly visible in this eclipse, with 33% of the Moon in shadow; the partial eclipse lasted for 2 hours and 15 minutes.

A **partial lunar eclipse** took place on July 17, 1981, the second of two lunar eclipses in 1981. The Earth's shadow on the moon was clearly visible in this eclipse, with 55% of the Moon in shadow; the partial eclipse lasted for 2 hours and 43 minutes.

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.

A **partial lunar eclipse** took place on July 6, 1963 with an umbral eclipse magnitude of 0.70602. The Moon was strikingly shadowed in this deep partial eclipse which lasted 3 hours exactly, with 71% of the Moon in darkness at maximum. A partial lunar eclipse occurs when the Earth moves between the Sun and Moon but the three celestial bodies do not form a straight line in space. When that happens, a small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow, called the umbra. The rest of the Moon is covered by the outer part of the Earth's shadow called the penumbra. It was the second of three lunar eclipses in 1963, the first was a penumbral lunar eclipse on January 9, 1963 and the third and last was on December 30, 1963.

A **total lunar eclipse** took place on November 7, 1957. The Moon barely edged into total eclipse for 27 minutes and 54 seconds. With the Moon just 3% 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 and 27 minutes in total.

A partial lunar eclipse took place on August 5, 1952. The Earth's shadow on the moon was clearly visible in this eclipse, with 53.2% of the Moon in shadow; the partial eclipse lasted for 2 hours and 27 minutes. The moon's apparent diameter was larger and Supermoon because the eclipse occurred only 45 minutes before perigee.

A total lunar eclipse took place on July 26, 1953.

A **partial lunar eclipse** will take place on January 22, 2046.

A **partial lunar eclipse** will take place on June 26, 2048. The Moon will be strikingly shadowed in this deep partial eclipse lasting 2 hours and 39 minutes, with 64% of the Moon in darkness at maximum.

A **total lunar eclipse** will take place on April 26, 2051.

A **total lunar eclipse** will take place on October 30, 2050.

**Gamma** of an eclipse describes how centrally the shadow of the Moon or Earth strikes the other body. This distance, measured at the moment when the axis of the shadow cone passes closest to the center of the Earth or Moon, is stated as a fraction of the equatorial radius of the Earth or Moon.

**Éphéméride Lunaire Parisienne** is a lunar theory developed by Jean Chapront, Michelle Chapront-Touzé, and others at the Bureau des Longitudes in the 1970s to 1990s.

A **penumbral lunar eclipse** will take place on August 29, 2053.
