June 2029 lunar eclipse

A total lunar eclipse will occur at the Moon’s ascending node of orbit on Tuesday, June 26, 2029,^[1] with an umbral magnitude of 1.8452. It will be a central lunar eclipse, in which part of the Moon will pass through the center of the Earth's shadow. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring about 3.7 days before perigee (on June 22, 2029, at 11:30 UTC), the Moon's apparent diameter will be larger.^[2]

Totality will last 1 hour, 41 minutes, and 53 seconds, the maximum duration for Saros series 130. The eclipse will plunge the full Moon into deep darkness, as it passes right through the center 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 color at maximum eclipse.

With an umbral eclipse magnitude of 1.84520, this is the largest lunar eclipse of the 21st century. Gamma has a value of only 0.01240. Due to the Moon's relatively large size as seen from Earth and greater speed in its elliptical orbit, totality will not last over 106 minutes. This is the darkest and greatest total lunar eclipse in the 21st century.

During the eclipse, NGC 6629 will be occulted by the Moon over the Pacific Ocean and South America. Deep-sky objects are rarely occulted during a total eclipse from any given spot on Earth.^[3]: 161

Visibility

The eclipse will be completely visible over eastern North America, South America, and west Africa, seen rising over western and central North America and the eastern Pacific Ocean and setting over Africa, Europe, and the Middle East.^[4]

Eclipse season

See also: Eclipse cycle

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight. The first and last eclipse in this sequence is separated by one synodic month.

Lunar eclipses of 2027–2031

This eclipse is a member of a semester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.^[6]

The penumbral lunar eclipses on February 20, 2027 and August 17, 2027 occur in the previous lunar year eclipse set, and the penumbral lunar eclipses on May 7, 2031 and October 30, 2031 occur in the next lunar year eclipse set.

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.

Saros 130

This eclipse is a part of Saros series 130, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on June 10, 1416. It contains partial eclipses from September 4, 1560 through April 12, 1903; total eclipses from April 22, 1921 through September 11, 2155; and a second set of partial eclipses from September 21, 2173 through May 10, 2552. The series ends at member 71 as a penumbral eclipse on July 26, 2678.

The longest duration of totality will be produced by member 35 at 101 minutes, 53 seconds on June 26, 2029. All eclipses in this series occur at the Moon’s ascending node of orbit.^[7]

Tritos series

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.

Inex series

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.
