A total [lunar eclipse](/source/Lunar_eclipse) occurred at the Moon’s [descending node](/source/Lunar_node) of orbit on Monday, November 7, 1938,[1] with an umbral [magnitude](/source/Magnitude_of_eclipse) of 1.3525. A lunar eclipse occurs when the [Moon](/source/Moon) moves into the [Earth's shadow](/source/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](/source/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](/source/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](/source/Umbra,_penumbra_and_antumbra) is smaller. Occurring about 3.2 days before [perigee](/source/Apsis) (on November 11, 1938, at 3:25 UTC), the Moon's apparent diameter was larger.[2]

This lunar eclipse was the second of an [almost tetrad](/source/Tetrad_(astronomy)), with the others being on [May 14, 1938](/source/May_1938_lunar_eclipse) (total); [May 3, 1939](/source/May_1939_lunar_eclipse) (total); and [October 28, 1939](/source/October_1939_lunar_eclipse) (partial).

## Visibility

The eclipse was completely visible over [Africa](/source/Africa), [Europe](/source/Europe), and [west](/source/West_Asia) and [central Asia](/source/Central_Asia), seen rising over [North](/source/North_America) and [South America](/source/South_America) and setting over [east Asia](/source/East_Asia) and western [Australia](/source/Australia).[3]

## Eclipse details

Shown below is a table displaying details about this particular solar eclipse. It describes various parameters pertaining to this eclipse.[4]

## Eclipse season

See also: [Eclipse cycle](/source/Eclipse_cycle)

This eclipse is part of an [eclipse season](/source/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](/source/Fortnight).

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a [half saros](/source/Saros_(astronomy)#Relationship_between_lunar_and_solar_saros_.28sar.29)).[5] This lunar eclipse is related to two annular solar eclipses of [Solar Saros 132](/source/Solar_Saros_132).
