A total lunar eclipse occurred at the Moon’s ascending node of orbit on Wednesday, June 15, 2011,{{cite web|title=June 15–16, 2011 Total Lunar Eclipse (Blood Moon)|url=https://www.timeanddate.com/eclipse/lunar/2011-june-15|publisher=timeanddate|access-date=15 November 2024}} with an umbral magnitude of 1.7014. 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 4.1 days after perigee (on June 11, 2011, at 21:40 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=2011&n=136|publisher=timeanddate|access-date=15 November 2024}}
The last time a lunar eclipse was closer to the center of the Earth's shadow was on July 16, 2000. The next central total lunar eclipse occurred on July 27, 2018.
Visibility and viewing
The eclipse was completely visible over east Africa, Antarctica, and west, central, and south Asia, seen rising over Europe, west Africa, and South America and setting over east Asia and Australia.{{cite web|title=Total Lunar Eclipse of 2011 Jun 15|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2011Jun15T.pdf|publisher=NASA|access-date=15 November 2024}}
In western Asia, Australia, and the Philippines, the lunar eclipse was visible just before sunrise.[http://www.heraldsun.com.au/news/more-news/longest-lunar-eclipse-for-a-decade-for-south-australia-stargazers/story-fn7x8me2-1226075835237 "Longest lunar eclipse for a decade turns moon blood red"], Terry Brown. Clare Peddie. Herald Sun. 16 June 2011. Accessed 15 June 2011 It was very visible in the clear and cloudless night sky throughout eastern and southeast Asia. Africa, far eastern Russia and Europe witnessed the whole event even in the late stages (as in partial lunar eclipse). The Americas (including North and northwestern South America) missed the eclipse completely (except in most areas) because it occurred at moonset.

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. The first and last eclipse in this sequence is separated by one synodic month.
