A total lunar eclipse will occur at the Moon’s descending node of orbit on Saturday, October 8, 2033, with an umbral magnitude of 1.3508. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. 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. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring only about 3 hours after perigee (on October 8, 2033, at 8:15 UTC), the Moon's apparent diameter will be larger.
This lunar eclipse is the last of a tetrad, with four total lunar eclipses in series, the others being on April 25, 2032; October 18, 2032; and April 14, 2033.
This will also be a supermoon, the first supermoon lunar eclipse by all definitions since May 26, 2021, unlike May 16 in 2022, which was defined by only some as taking place during a supermoon.
