July 2000 lunar eclipse
Template:Short description Template:Use dmy dates Template:Infobox lunar eclipse A total lunar eclipse occurred at the Moon’s descending node of orbit on Sunday, July 16, 2000,[1] with an umbral magnitude of 1.7684. It was a central lunar eclipse, in which part of the Moon passed through the center of the Earth's shadow. 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 shadow is smaller. Occurring about 1.1 days after apogee (on July 15, 2000, at 11:30 UTC), the Moon's apparent diameter was smaller.[2]
Totality lasted for 106 minutes and 25 seconds, the longest duration since 13 August 1859 (106 minutes and 28 seconds) and 3 May 459 (106 minutes and 32 seconds), and totality of this length won't occur again until 19 August 4753 (106 minutes and 35 seconds). This was the last and longest total lunar eclipse of the 20th century as well as the second longest and last of the second millennium. It was also the eighth longest total lunar eclipse on EclipseWise's Six Millennium Catalog of Lunar Eclipses which covers the years 3000 BCE to 3000 AD. The longest total lunar eclipse between the years 4000 BCE and 6000 CE took place on 31 May 318. Totality lasted 106 minutes and 36 seconds which is only 11 seconds longer than this one.[3]
Visibility
The eclipse was completely visible over Australia, Antarctica, and much of the Pacific Ocean, seen rising over Asia and eastern Africa and setting over western North and South America.[4]

Eclipse season
Script error: No such module "Labelled list hatnote". 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. The first and last eclipse in this sequence is separated by one synodic month.
