A partial lunar eclipse occurred at the Moon’s ascending node of orbit on Saturday, October 28, 2023, with an umbral magnitude of 0.1234. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in 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 2.9 days after perigee (on October 25, 2023, at 23:00 UTC), the Moon's apparent diameter was larger.
