A total lunar eclipse occurred at the Moon’s descending node of orbit on Thursday, February 21, 2008,{{cite web|title=February 20–21, 2008 Total Lunar Eclipse (Blood Moon)|url=https://www.timeanddate.com/eclipse/lunar/2008-february-21|publisher=timeanddate|access-date=14 November 2024}} with an umbral magnitude of 1.1081. 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. The Moon's apparent diameter was near the average diameter because it occurred 7.2 days after perigee (on February 13, 2008, at 20:00 UTC) and 6.8 days before apogee (on February 27, 2008, at 20:30 UTC).{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=2007&n=136|publisher=timeanddate|access-date=14 November 2024}}

Visibility

The eclipse was completely visible over North and South America, west Africa, and western Europe, seen rising over much of the Pacific Ocean and setting over much of Africa, eastern Europe, and west, central, and south Asia.{{cite web|title=Total Lunar Eclipse of 2008 Feb 21|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2008Feb21T.pdf|publisher=NASA|access-date=14 November 2024}}

The bright star Regulus of Leo and the planet Saturn were prominent very near the Moon during the total eclipse portion. Shortly before the eclipse began, Regulus was occulted by the Moon in parts of the far Southern Atlantic Ocean and Antarctica.

Timing

The Moon entered the penumbral shadow at 0:36 UTC, and the umbral shadow at 1:43. Totality lasted for 50 minutes, between 3:01 and 3:51. The Moon left the umbra shadow at 5:09 and left the penumbra shadow at 6:16.{{cite web|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2008Feb21T.pdf|title=Total lunar eclipse of 2008 Feb 21|date=2008-02-21|publisher=NASA}} Eclipse Predictions by Fred Espenak, NASA's GSFC

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.
