April 2034 lunar eclipse

A penumbral lunar eclipse will occur at the Moon’s ascending node of orbit on Monday, April 3, 2034,^[1] with an umbral magnitude of −0.2263. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's penumbra. 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. Occurring about 2.2 days before apogee (on April 5, 2034, at 23:45 UTC), the Moon's apparent diameter will be smaller.^[2]

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.

Lunar eclipses of 2031–2034

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.^[5]

The penumbral lunar eclipse on June 5, 2031 occurs in the previous lunar year eclipse set.

Saros 142

This eclipse is a part of Saros series 142, repeating every 18 years, 11 days, and containing 73 events. The series started with a penumbral lunar eclipse on September 19, 1709. It contains partial eclipses from May 5, 2088 through July 10, 2196; total eclipses from July 22, 2214 through April 21, 2665; and a second set of partial eclipses from May 3, 2683 through July 29, 2827. The series ends at member 73 as a penumbral eclipse on November 17, 3007.

The longest duration of totality will be produced by member 34 at 103 minutes, 54 seconds on September 15, 2304. All eclipses in this series occur at the Moon’s ascending node of orbit.^[6]

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.

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.
