A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Saturday, February 11, 2017,{{cite web|title=February 10–11, 2017 Penumbral Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2017-february-11|publisher=timeanddate|access-date=16 November 2024}} with an umbral magnitude of −0.0342. It was not quite a total penumbral lunar eclipse. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into 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 4.6 days before perigee (on February 6, 2017, at 9:00 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=2017&n=136|publisher=timeanddate|access-date=16 November 2024}}
This eclipse occurred the same day as comet 45P/Honda–Mrkos–Pajdušáková made a close approach to Earth (0.08318 AU). It also occurred on the Lantern Festival, the first eclipse to do so since February 9, 2009.
Visibility
The eclipse was completely visible over northeastern North America, eastern South America, Europe, Africa, and west Asia, seen rising over much of North America and western South America and setting over south and east Asia.{{cite web|title=Penumbral Lunar Eclipse of 2017 Feb 11|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2017Feb11N.pdf|publisher=NASA|access-date=17 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.
