A partial [[lunar eclipse]] occurred at the Moon’s [[Lunar node|descending node]] of orbit on Thursday, July 5, 2001,<ref>{{cite web|title=July 5–6, 2001 Partial Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2001-july-5|publisher=timeanddate|access-date=12 November 2024}}</ref> with an umbral [[Magnitude of eclipse|magnitude]] of 0.4961. 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 3.7 days before [[Apsis|apogee]] (on July 9, 2001, at 7:20 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=2001&n=136|publisher=timeanddate|access-date=12 November 2024}}</ref>

== Visibility ==
The eclipse was completely visible over [[east Asia]], [[Australia]], and [[Antarctica]], seen rising over [[east Africa]] and [[west Asia|west]] and [[central Asia]] and setting over western [[North America]].<ref>{{cite web|title=Partial Lunar Eclipse of 2001 Jul 05|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2001Jul05P.pdf|publisher=NASA|access-date=12 November 2024}}</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]].
