- Source: November 1937 lunar eclipse
A partial lunar eclipse occurred at the Moon’s descending node of orbit on Thursday, November 18, 1937, with an umbral magnitude of 0.1443. 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 only about 18 hours before perigee (on November 19, 1937, at 0:30 UTC), the Moon's apparent diameter was larger.
Visibility
The eclipse was completely visible over much of northeast Asia, North America, and northwestern South America, seen rising over east Asia and Australia and setting over much of South America, west Africa, and western 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.
