• Source: October 2013 lunar eclipse

A penumbral lunar eclipse occurred at the Moon’s descending node of orbit on Friday, October 18, 2013, with an umbral magnitude of −0.2706. 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. The Moon's apparent diameter was near the average diameter because it occurred 8.2 days after perigee (on October 10, 2013, at 19:15 UTC) and 6.9 days before apogee (on October 25, 2013, at 10:25 UTC).




Visibility


The eclipse was completely visible over Africa, Europe, eastern South America, and west Asia, seen rising over western South America and North America and setting over south and east Asia.

Eclipse details


Shown below is a table displaying details about this particular solar eclipse. It describes various parameters pertaining to this eclipse.




Eclipse season



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 lunar year series repeats after 12 lunations or 354 days (Shifting back about 10 days in sequential years). Because of the date shift, the Earth's shadow will be about 11 degrees west in sequential events.




= Half-Saros cycle

=
A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros). This lunar eclipse is related to two partial solar eclipses of Solar Saros 124.
