A total [[lunar eclipse]] will occur at the Moon’s [[Lunar node|descending node]] of orbit on Saturday, May 26, 2040,<ref>{{cite web|title=May 26, 2040 Total Lunar Eclipse (Blood Moon)|url=https://www.timeanddate.com/eclipse/lunar/2040-may-26|publisher=timeanddate|access-date=1 December 2024}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of 1.5365. It will be a [[List of central lunar eclipses|central lunar eclipse]], in which part of the [[Moon]] will pass through the [[antisolar point|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 [[Umbra, penumbra and antumbra|shadow]] is smaller. Occurring about 1.4 days before [[Apsis|perigee]] (on May 27, 2040, at 22:25 UTC), the Moon's apparent diameter will be larger.<ref>{{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}}</ref>

This is the second central lunar eclipse of [[Lunar Saros 131|Saros series 131]]. Since this lunar event will occur near [[Apsis|perigee]], it will be referred to as a "super flower blood moon" or "super blood moon", though not quite as close to Earth as the eclipse of [[May 2021 lunar eclipse|May 26, 2021]].

== Visibility ==
The eclipse will be completely visible over [[Antarctica]], [[Australia]], and the [[Pacific Ocean]], seen rising over [[east Asia|east]] and [[south Asia]] and setting over [[North America|North]] and [[South America]].<ref>{{cite web|title=Total Lunar Eclipse of 2040 May 26|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2040May26T.pdf|publisher=NASA|access-date=1 December 2024}}</ref>

== 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]].
