A partial [[lunar eclipse]] occurred at the Moon’s [[Lunar node|ascending node]] of orbit on Saturday, August 27, 1988,<ref>{{cite web|title=August 26–27, 1988 Partial Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/1988-august-27|publisher=timeanddate|access-date=7 January 2025}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of 0.2916. 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 7 hours before [[Apsis|perigee]] (on August 17, 1988, at 17:50 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=1988&n=136|publisher=timeanddate|access-date=7 January 2025}}</ref>

== Visibility ==
The eclipse was completely visible over eastern [[Australia]], western [[North America]], and much of the [[Pacific Ocean]], seen rising over western Australia and the eastern half of [[Asia]] and setting over much of North America and [[South America]].<ref>{{cite web|title=Partial Lunar Eclipse of 1988 Aug 27|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot1951/LE1988Aug27P.pdf|publisher=NASA|access-date=7 January 2025}}</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]].
