A penumbral [[lunar eclipse]] occurred at the Moon’s [[Lunar node|descending node]] of orbit on Friday, May 5, 2023,<ref>{{cite web|title=May 5–6, 2023 Penumbral Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2023-may-5|publisher=timeanddate|access-date=18 November 2024}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of −0.0438. 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 5.2 days before [[Apsis|perigee]] (on May 11, 2023, at 1:05 UTC), the Moon's apparent diameter was larger.<ref>{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=2023&n=136|publisher=timeanddate|access-date=18 November 2024}}</ref>

This was the deepest penumbral eclipse (with –0.0438 magnitude) since [[February 2017 lunar eclipse|February 2017]] and until [[August 2053 lunar eclipse|August 2053]].<ref>{{cite web | url=https://www.timeanddate.com/eclipse/lunar/2023-may-5 | title=Penumbral Lunar Eclipse on May 5–6, 2023 – Where and when to See }}</ref>

== Visibility ==
The eclipse was completely visible over [[Asia]], [[Australia]], and [[Antarctica]], seen rising over [[Africa]] and [[Europe]] and setting over the central [[Pacific Ocean]].<ref>{{cite web|title=Penumbral Lunar Eclipse of 2023 May 05|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2023May05N.pdf|publisher=NASA|access-date=18 November 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]].
