Penumbral lunar eclipse 2013: April 25 marks first lunar eclipse
The first penumbral lunar eclipse of 2013 will take place on April 25. It will last for 27 minutes and be visible in Europe, Africa, Asia and Australia.
There are three types of lunar eclipse: total lunar eclipse, partial lunar eclipse andpenumbral lunar eclipse. When the Moon totally enters the umbra (the full shadow) of the Earth, it is a total lunar eclipse; When only part of the moon passes into the umbra, it is a partial lunar eclipse.
The prenumbral lunar eclipse describes a phenomenon when the Moon only enters the penumbra of the Earth. During a penumbral lunar eclipse, the brightness of the Moon is only marginally reduced. While it is nearly unnoticeable to the naked eyes, the change in brightness can be recorded accurately by a camera.
A partial lunar eclipse this shallow hasn’t occurred since May 3rd, 1958 (0.9%) and won’t be topped until September 28th, 2034 (1.4%). This is the second slightest partial lunar eclipse for this century.
This penumbral eclipse is also the second shortest partial eclipse of the Moon for the 21st century, lasting 27 minutes.
