- Source: January 2000 lunar eclipse
A total lunar eclipse occurred at the Moon’s ascending node of orbit on Friday, January 21, 2000, with an umbral magnitude of 1.3246. 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 1.5 days after perigee (on January 19, 2000, at 17:50 UTC), the Moon's apparent diameter was larger.
Visibility
The eclipse was completely visible over most of North America, South America, and western Europe, seen rising over the Pacific Ocean and setting over Africa, Europe, and west Asia.
Eclipse details
Shown below is a table displaying details about this particular solar eclipse. It describes various parameters pertaining to this eclipse.
Eclipse season
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.

== Tritos series
=The tritos series repeats 31 days short of 11 years at alternating nodes. Sequential events have incremental Saros cycle indices.
This series produces 20 total eclipses between April 24, 1967 and August 11, 2185, only being partial on November 19, 2021.
= Half-Saros cycle
=A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half-saros). This lunar eclipse is related to two annular solar eclipses of Solar Saros 131.
