A penumbral lunar eclipse will occur at the Moon’s descending node of orbit on Thursday, June 17, 2038,[1] with an umbral magnitude of −0.5259. 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 2.7 days after perigee (on June 14, 2038, at 11:30 UTC), the Moon's apparent diameter will be larger.[2]

This eclipse will be the second of four penumbral lunar eclipses in 2038, with the others occurring on January 21, July 16, and December 11.

Visibility

The eclipse will be completely visible over eastern North America, South America, west and southern Africa, and western Europe, seen rising over western North America and the eastern Pacific Ocean and setting over northeast Africa, eastern Europe, and the Middle East.[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. The first and last eclipse in this sequence is separated by one synodic month.

Lunar Saros 111, repeating every 18 years and 11 days, has a total of 71 lunar eclipse events including 11 total lunar eclipses. The first total lunar eclipse of this series was on April 19, 1353, and last was on August 4, 1533. The longest occurrence of this series was on June 12, 1443 when the totality lasted 106 minutes.

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 total solar eclipses of Solar Saros 118.
