A total lunar eclipse will occur at the Moon’s ascending node of orbit on Saturday, January 31, 2037, with an umbral magnitude of 1.2086. 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 only about 12 hours before perigee (on February 1, 2037, at 2:00 UTC), the Moon's apparent diameter will be larger. This lunar eclipse will be the third of an almost tetrad, with the others being on February 11, 2036 (total); August 7, 2036 (total); and July 27, 2037 (partial). This eclipse occurs during a supermoon and a blue moon (second full moon of month), of which the most recent occurrence was on January 31, 2018, one previous metonic cycle (19 years).

Visibility

The eclipse will be completely visible over east and northeast Asia, Australia, and northwestern North America, seen rising over west Asia, eastern Europe, and east Africa and setting over most of North America and the eastern Pacific Ocean.

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.
