January 1963 lunar eclipse
Template:Short description Template:Infobox lunar eclipse A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Wednesday, January 9, 1963,[1] with an umbral magnitude of −0.0184. It was a relatively rare total penumbral lunar eclipse, with the Moon passing entirely within the penumbral shadow without entering the darker umbral shadow.[2] A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into 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 about 5.6 days after perigee (on January 4, 1963, at 8:25 UTC), the Moon's apparent diameter was larger.[3]
Visibility
The eclipse was completely visible over northeastern North America, Europe, Africa, and the western half of Asia, seen rising over North and South America and setting over east and southeast Asia and western Australia.[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 1962–1965
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 penumbral lunar eclipses on February 19, 1962 and August 15, 1962 occur in the previous 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 121.
