Visibility

The eclipse is currently completely visible over most of North and South America, seen rising over Northwest North America, and the Pacific Ocean, and will set over Africa and Europe.

Lunar year series

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.^[1]

The penumbral lunar eclipses on January 10, 2020 and July 5, 2020 occur in the previous lunar year eclipse set.

This eclipse is a part of Saros series 131, repeating every 18 years, 11 days, and containing 72 events. The series started with a penumbral lunar eclipse on May 10, 1427. It contains partial eclipses from July 25, 1553 through March 22, 1932; total eclipses from April 2, 1950 through September 3, 2202; and a second set of partial eclipses from September 13, 2220 through April 9, 2563. The series ends at member 72 as a penumbral eclipse on July 7, 2707.

The longest duration of totality will be produced by member 38 at 100 minutes, 36 seconds on June 28, 2094. All eclipses in this series occur at the Moon’s descending node of orbit.^[2]

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.

This is the first of the series that passes through the center of the Earth's shadow. The last occurrence was on May 2004 lunar eclipse. The next occurrence is May 2040 lunar eclipse.

Metonic series

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

The Moon's path through the Earth's shadow near its descending node progresses southward through each sequential eclipse. The second and third are total eclipses.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).^[4] This lunar eclipse is related to two annular solar eclipses of Solar Saros 138.
