A total lunar eclipse occurred at the Moon’s ascending node of orbit on Tuesday, January 9, 2001,{{cite web|title=January 9–10, 2001 Total Lunar Eclipse (Blood Moon)|url=https://www.timeanddate.com/eclipse/lunar/2001-january-9|publisher=timeanddate|access-date=12 November 2024}} with an umbral magnitude of 1.1902. 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 only about 8 hours before perigee (on January 10, 2001, at 4:00 UTC), the Moon's apparent diameter was larger.{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=2001&n=136|publisher=timeanddate|access-date=12 November 2024}}
Visibility
The eclipse was completely visible over Africa, Europe, and Asia, seen rising over eastern and northern North America and eastern South America and setting over Australia and the western Pacific Ocean.{{cite web|title=Total Lunar Eclipse of 2001 Jan 09|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2001Jan09T.pdf|publisher=NASA|access-date=12 November 2024}}

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.
