A total lunar eclipse will occur at the Moon’s descending node of orbit on Sunday, December 31, 2028,[1] with an umbral magnitude of 1.2479. 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 4.3 days before perigee (on January 4, 2029, at 23:15 UTC), the Moon's apparent diameter will be larger.[2]
This eclipse will occur during a blue moon and is the first such eclipse to happen on New Year's Eve and New Year's Day since December 2009, and the first total lunar eclipse on New Year's Day in history. The next such eclipse will be in December 2047 (though January 2048 for most timezones).
Visibility
[edit]The eclipse will be completely visible over eastern Europe, Asia, and Australia, seen rising over Africa and Europe and setting over the eastern Pacific Ocean and western North America.[3]

Eclipse season
[edit]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.
