Wikipedia / October 1966 lunar eclipse
A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Saturday, October 29, 1966, with an umbral magnitude of −0.1249. 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 4 days after apogee (on October 25, 1966, at 9:55 UTC), the Moon's apparent diameter was smaller.
Visibility
The eclipse was completely visible over northeast Asia, much of North America, and the Pacific Ocean, seen rising over east and southeast Asia and Australia and setting over eastern North America and South America.

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.
