A penumbral [[lunar eclipse]] occurred at the Moon’s [[Lunar node|ascending node]] of orbit on Saturday, March 1, 1980,<ref>{{cite web|title=March 1–2, 1980 Penumbral Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/1980-march-1|publisher=timeanddate|access-date=4 January 2025}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of −0.4404. 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 1.6 days before [[Apsis|apogee]] (on March 3, 1980, at 10:50 UTC), the Moon's apparent diameter was smaller.<ref>{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=1980&n=136|publisher=timeanddate|access-date=4 January 2025}}</ref>

== Visibility ==
The eclipse was completely visible over [[Africa]], [[Europe]], and much of [[Asia]], seen rising over northeastern [[North America]] and eastern [[South America]] and setting over [[northeast Asia]] and [[Australia]].<ref>{{cite web|title=Penumbral Lunar Eclipse of 1980 Mar 01|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot1951/LE1980Mar01N.pdf|publisher=NASA|access-date=4 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]].
