A partial lunar eclipse occurred at the Moon’s descending node of orbit on Thursday, July 5, 2001,[1] with an umbral magnitude of 0.4961. 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 3.7 days before apogee (on July 9, 2001, at 7:20 UTC), the Moon's apparent diameter was smaller.[2]
