A total lunar eclipse occurred at the Moon’s descending node of orbit on Friday, May 16, 2003,[1] with an umbral magnitude of 1.1294. 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 15 hours after perigee (on May 15, 2003, at 11:40 UTC), the Moon's apparent diameter was larger.[2]
This lunar eclipse marks the beginning of a tetrad, with four total lunar eclipses in series, the others being on November 9, 2003; May 4, 2004; and October 28, 2004. The previous series was in 1985 and 1986, starting with the May 1985 lunar eclipse. The next series was in 2014 and 2015, starting with the April 2014 lunar eclipse.
