A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Wednesday, August 27, 1969, with an umbral magnitude of −0.9514. 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 2.25 days after perigee (on August 25, 1969, at 16:30 UTC), the Moon's apparent diameter was larger.
This was the last lunar eclipse of Lunar Saros 108.
Visibility The eclipse was completely "visible" over east and northeast Asia, Australia, western and central North America, western South America, and Antarctica.
"Visible" is quoted here as a magnitude of 1.3% in the penumbra is not discernible at all with the human eye. It means the parts of the world where the full Moon was above the horizon, just looking like an uneclipsed Moon.

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. The first and last eclipse in this sequence is separated by one synodic month.
