A penumbral [[lunar eclipse]] will occur at the Moon’s [[Lunar node|ascending node]] of orbit on Thursday, January 21, 2038,<ref>{{cite web|title=January 20–21, 2038 Penumbral Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2038-january-21|publisher=timeanddate|access-date=29 November 2024}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of −0.1127. 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 3.1 days before [[Apsis|perigee]] (on January 24, 2038, at 4:50 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=2038&n=136|publisher=timeanddate|access-date=29 November 2024}}</ref>

This eclipse will be the first of four penumbral lunar eclipses in 2038, with the others occurring on [[June 2038 lunar eclipse|June 17]], [[July 2038 lunar eclipse|July 16]], and [[December 2038 lunar eclipse|December 11]].

== Visibility ==
The eclipse will be completely visible over [[North America|North]] and [[South America]], [[west Africa]], and [[Europe]], seen rising over the eastern [[Pacific Ocean]] and setting over [[east Africa]] and [[west Asia|west]] and [[central Asia]].<ref>{{cite web|title=Penumbral Lunar Eclipse of 2038 Jan 21|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2038Jan21N.pdf|publisher=NASA|access-date=29 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]].
