- Source: July 2037 lunar eclipse
A partial lunar eclipse will occur at the Moon’s descending node of orbit on Monday, July 27, 2037, with an umbral magnitude of 0.8108. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in 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 4.1 days before apogee (on July 31, 2037, at 8:30 UTC), the Moon's apparent diameter will be smaller.
This lunar eclipse will be the last of an almost tetrad, with the others being on February 11, 2036 (total); August 7, 2036 (total); and January 31, 2037 (total).
Visibility
The eclipse will be completely visible over eastern North America and South America, seen rising over western North America and the eastern Pacific Ocean and setting over Africa and Europe.
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.
