October 2051 lunar eclipse


A total lunar eclipse will occur at the Moon’s descending node of orbit on Thursday, October 19, 2051, with an umbral magnitude of 1.4130. It will be a central lunar eclipse, in which part of the Moon will pass through the center of the Earth's shadow. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. 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. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring only about 30 minutes after perigee, the Moon's apparent diameter will be larger.
This lunar eclipse is the last of a tetrad, with four total lunar eclipses in series, the others being on May 6, 2050; October 30, 2050; and April 26, 2051.
This will be the first central eclipse of Saros series 137. Less than a day from perigee, the Moon's apparent diameter will be larger, and be considered a supermoon.

Visibility

The eclipse will be completely visible over east Africa and much of Europe and Asia, seen rising over eastern South America and west Africa and setting over Australia and the western Pacific Ocean.

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.
