A total [[lunar eclipse]] occurred at the Moon’s [[Lunar node|descending node]] of orbit on Saturday, September 16, 1978,<ref>{{cite web|title=September 16–17, 1978 Total Lunar Eclipse (Blood Moon)|url=https://www.timeanddate.com/eclipse/lunar/1978-september-16|publisher=timeanddate|access-date=4 January 2025}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of 1.3268. A lunar eclipse occurs when the [[Moon]] moves into the [[Earth's shadow]], causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. 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. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's [[Umbra, penumbra and antumbra|shadow]] is smaller. Occurring about 2.4 days after [[Apsis|perigee]] (on September 14, 1978, at 10:35 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=1978&n=136|publisher=timeanddate|access-date=4 January 2025}}</ref>

== Visibility ==
The eclipse was completely visible over [[east Africa]], [[eastern Europe]], much of [[Asia]], and western [[Australia]], seen rising over eastern [[South America]], [[western Europe]], and [[west Africa|west]] and [[central Africa]] and setting over [[northeast Asia]] and central and eastern Australia.<ref>{{cite web|title=Total Lunar Eclipse of 1978 Sep 16|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot1951/LE1978Sep16T.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]].
