A partial [[lunar eclipse]] will occur at the Moon’s [[Lunar node|descending node]] of orbit on Wednesday, January 12, 2028,<ref>{{cite web|title=January 11–12, 2028 Partial Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2028-january-12|publisher=timeanddate|access-date=19 November 2024}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of 0.0679. A lunar eclipse occurs when the [[Moon]] moves into the [[Earth's shadow]], causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in 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 only about 22.5 hours before [[Apsis|perigee]] (on January 13, 2028, at 2:45 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=2028&n=136|publisher=timeanddate|access-date=19 November 2024}}</ref>

== Visibility ==
The eclipse will be completely visible over [[North America|North]] and [[South America]], [[west Africa]], and [[Europe]], seen rising over the central [[Pacific Ocean]] and setting over [[central Africa|central]] and [[east Africa]] and [[west Asia|west]] and [[central Asia]].<ref>{{cite web|title=Partial Lunar Eclipse of 2028 Jan 12|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2028Jan12P.pdf|publisher=NASA|access-date=19 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]].
