A total lunar eclipse occurred at the Moon’s ascending node of orbit on Tuesday, March 3, 1942,[1] with an umbral magnitude of 1.5612. 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 5.5 days before perigee (on March 8, 1942, at 11:50 UTC), the Moon's apparent diameter was larger.[2]
This was a central lunar eclipse, with the Moon passing through the darkest portion of the earth's umbral shadow.
Visibility
[edit]The eclipse was completely visible over eastern South America, Africa, Europe, and the Middle East, seen rising over North America and west and central South America and setting over much of Asia and western Australia.[3]

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

| Penumbral Magnitude | 2.58789 |
| Umbral Magnitude | 1.56118 |
| Gamma | −0.15453 |

| Sun Semi-Diameter | 16'08.0" |
| Sun Equatorial Horizontal Parallax | 08.9" |

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.
