A partial [[lunar eclipse]] occurred at the Moon’s [[Lunar node|ascending node]] of orbit on Tuesday, March 13, 1979,<ref>{{cite web|title=March 13–14, 1979 Partial Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/1979-march-13|publisher=timeanddate|access-date=4 January 2025}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of 0.8538. 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 about 3.5 days after [[Apsis|apogee]] (on March 10, 1979, at 10:20 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=1979&n=136|publisher=timeanddate|access-date=4 January 2025}}</ref>

== Visibility ==
The eclipse was completely visible over much of [[Africa]], [[Europe]], and the western half of [[Asia]], seen rising over eastern [[North America]], [[South America]], and [[west Africa]] and setting over [[east Asia|east]] and [[northeast Asia]] and [[Australia]].<ref>{{cite web|title=Partial Lunar Eclipse of 1979 Mar 13|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot1951/LE1979Mar13P.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]].
