August 1951 lunar eclipse
A penumbral lunar eclipse will occur at the Moon’s ascending node of orbit on Friday, August 17, 1951,[1] with an umbral magnitude of −0.8455. 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 1.9 days after perigee (on August 15, 1951, at 5:05 UTC), the Moon's apparent diameter was larger.[2] This eclipse was the third of four penumbral lunar eclipses in 1951, with the others occurring on February 21, March 23, and September 15. VisibilityThe eclipse was completely visible over eastern and central North America, South America, western Europe, and much of Africa, seen rising over northwestern North America and setting over Eastern Europe, east Africa, and the Middle East.[3]
Eclipse detailsShown below is a table displaying details about this particular solar eclipse. It describes various parameters pertaining to this eclipse.[4]
Eclipse seasonThis 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. The first and last eclipse in this sequence is separated by one synodic month.

Metonic seriesThis is the third of five Metonic lunar eclipses. The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the Earth's shadow will in nearly the same location relative to the background stars.
Half-Saros cycleA lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[5] This lunar eclipse is related to one partial solar eclipse of Solar Saros 115.
