A partial lunar eclipse will occur at the Moon’s descending node of orbit on Thursday, May 16, 2041,[1] with an umbral magnitude of 0.0663. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in 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 5.8 days before perigee (on May 21, 2041, at 21:20 UTC), the Moon's apparent diameter will be larger.[2]

Visibility

The eclipse will be completely visible over South America, Europe, and Africa, seen rising over much of North America and setting over west, central, and South Asia.[3]

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 2038–2042

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 eclipses on January 21, 2038 and July 16, 2038 occur in the previous lunar year eclipse set, and the penumbral lunar eclipses on April 5, 2042 and September 29, 2042 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 141

This eclipse is a part of Saros series 141, repeating every 18 years, 11 days, and containing 72 events. The series started with a penumbral lunar eclipse on August 25, 1608. It contains partial eclipses from May 16, 2041 through July 20, 2149; total eclipses from August 1, 2167 through May 1, 2618; and a second set of partial eclipses from May 12, 2636 through July 16, 2744. The series ends at member 72 as a penumbral eclipse on October 11, 2888.

The longest duration of totality will be produced by member 39 at 104 minutes, 36 seconds on October 16, 2293. All eclipses in this series occur at the Moon’s descending 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.
