A total lunar eclipse occurred at the Moon’s ascending node of orbit on Saturday, April 4, 2015,[1] with an umbral magnitude of 1.0019. 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 about 3.1 days after apogee (on April 1, 2015, at 9:00 UTC), the Moon's apparent diameter was smaller.[2]
This lunar eclipse is the third of a tetrad, with four total lunar eclipses in series, the others being on April 15, 2014; October 8, 2014; and September 28, 2015.
This is the 30th member of Lunar Saros 132, and the first total eclipse of the series. The previous event was the March 1997 lunar eclipse, being slightly partial.
