A total lunar eclipse will occur at the Moon’s ascending node of orbit on Sunday, November 18, 2040,{{cite web|title=November 18–19, 2040 Total Lunar Eclipse (Blood Moon)|url=https://www.timeanddate.com/eclipse/lunar/2040-november-18|publisher=timeanddate|access-date=1 December 2024}} with an umbral magnitude of 1.3991. 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 about 5.7 days before apogee (on November 24, 2040, at 14:10 UTC), the Moon's apparent diameter will be smaller.{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=2040&n=136|publisher=timeanddate|access-date=1 December 2024}}

This is the second central lunar eclipse of Saros series 136, the first taking place on November 8, 2022.

Visibility

The eclipse will be completely visible over east Africa, Europe, and Asia, seen rising over west Africa and eastern North and South America and setting over Australia and the western Pacific Ocean.{{cite web|title=Total Lunar Eclipse of 2040 Nov 18|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2040Nov18T.pdf|publisher=NASA|access-date=1 December 2024}}

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.
