    • Source: January 1955 lunar eclipse

      • A penumbral lunar eclipse will occur at the Moon’s descending node of orbit on Saturday, January 8, 1955, with an umbral magnitude of −0.1421. 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 2.2 days after perigee (on January 6, 1955, at 8:55 UTC), the Moon's apparent diameter was larger.


      Visibility


      The eclipse was completely visible over east and north Asia, Australia, and northwestern North America, seen rising over much of the western half of Asia and northern Europe and setting over eastern North America and northwestern South America.


      Eclipse details


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


      Eclipse season



      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.
