March 1960 lunar eclipse
Template:Short description Template:Infobox lunar eclipse A total lunar eclipse occurred at the Moon’s ascending node of orbit on Sunday, March 13, 1960,[1] 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 (on March 19, 1960, at 7:10 UTC), the Moon's apparent diameter was larger.[2]
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 (—57°C), significantly higher than the 160K (—113°C) in the area around the crater.[3]
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.[4]

Eclipse season
Script error: No such module "Labelled list hatnote". 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.

Lunar eclipses of 1958–1962
This eclipse is a member of a semester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[6]
The lunar eclipses on May 3, 1958 (partial) and October 28, 1958 (penumbral) occur in the previous lunar year eclipse set, and the penumbral lunar eclipse on July 17, 1962 occurs in the next lunar year eclipse set.

Half-Saros cycle
A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[7] This lunar eclipse is related to two total solar eclipses of Solar Saros 129.
