March 1960 lunar eclipse


A total lunar eclipse occurred at the Moon’s ascending node of orbit on Sunday, March 13, 1960, with an umbral magnitude of 1.5145. It was a central lunar eclipse, in which part of the Moon passed through the center of the Earth's shadow. 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 5.9 days before perigee, the Moon's apparent diameter was larger.
This eclipse afforded astrophysicist Richard W. Shorthill the opportunity to make the first infrared pyrometric temperature scans of the lunar surface, and led to his discovery of the first lunar "hot spot" observed from Earth. Shorthill found that the temperature of the floor of the Tycho crater was 216° Kelvin, significantly higher than the 160K in the area around the crater.

Visibility

The eclipse was completely visible over North America and the central and eastern Pacific Ocean, seen rising over east and northeast Asia and Australia and setting over South America, western Europe, and west Africa.

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.
