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

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.

Metonic series

This eclipse is the fourth and final of four Metonic cycle lunar eclipses on the same date, May 15–16, each separated by 19 years.

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.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).^[5] This lunar eclipse is related to two annular solar eclipses of Solar Saros 148.
