A total lunar eclipse will occur at the Moon’s descending node of orbit on Saturday, October 8, 2033, with an umbral magnitude of 1.3508. 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 only about 3 hours after perigee (on October 8, 2033, at 8:15 UTC), the Moon's apparent diameter will be larger.

This lunar eclipse is the last of a tetrad, with four total lunar eclipses in series, the others being on April 25, 2032; October 18, 2032; and April 14, 2033.

This will also be a supermoon, the first supermoon lunar eclipse by all definitions since May 26, 2021, unlike May 16 in 2022, which was defined by only some as taking place during a supermoon.

Visibility

The eclipse will be completely visible over northeast Asia, eastern Australia, western North America and the Pacific Ocean, seen rising over most of Asia and western Australia and setting over eastern North America and South America.

Saros 137

This eclipse is a part of Saros series 137, repeating every 18 years, 11 days, and containing 78 events. The series started with a penumbral lunar eclipse on December 17, 1564. It contains partial eclipses from June 10, 1835 through August 26, 1961; total eclipses from September 6, 1979 through June 28, 2466; and a second set of partial eclipses from July 9, 2484 through September 12, 2592. The series ends at member 78 as a penumbral eclipse on April 20, 2953.

The longest duration of totality will be produced by member 44 at 99 minutes, 53 seconds on April 13, 2340. All eclipses in this series occur at the Moon’s descending node of orbit.

Eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

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.
