A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Wednesday, March 23, 2016,{{cite web|title=March 23, 2016 Penumbral Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2016-march-23|publisher=timeanddate|access-date=16 November 2024}} with an umbral magnitude of −0.3107. 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 2 days before apogee (on March 25, 2016, at 10:15 UTC), the Moon's apparent diameter was smaller.{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=2016&n=136|publisher=timeanddate|access-date=16 November 2024}}
Visibility
The eclipse was completely visible over Australia and western North America, seen rising over much of Asia and setting over central and eastern North America and western South America.{{cite web|title=Penumbral Lunar Eclipse of 2016 Mar 23|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2016Mar23N.pdf|publisher=NASA|access-date=16 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.
