ASTRONOMY – This Friday evening a little before midnight, the Moon will enter the penumbra of the Earth : this is called an eclipse of the Moon in the penumbra. Explanations.
drafting LCI
If the Moon will be full this night, she will lose little by little its brightness. This Friday, shortly before midnight, the Moon will enter the penumbra of the Earth. Because of this, its surface will appear less bright than usual. The eclipse will begin around 23h34, at the time when the sun will align with the Sun and the Earth. It will reach its climax in 1h44, when 98% of the disk in heaven will be in darkness. Down here, those who scruteront will have the opportunity to see the satellite of the Earth will darken gradually.
However, the Moon is not passing only partly in the shadow cone, one can not speak of an eclipse of the Moon. In addition, it will not change its coloration, such as during a total eclipse, where the Moon is almost orange.
A phenomenon visible to the naked eye
Note that this celestial phenomenon, which takes place only two or three times per year, is to be observed safely with the naked eye. However, it is even more beautiful with a pair of binoculars or an astronomical telescope. To make the most of the show, find a dark area, away from artificial lights. Take a short twenty minutes for your pupils adjust to the darkness.
…or from the couch, warm
Those who do not want to set foot outside can still enjoy the show. The specialized site Slooh offers live transmission. It will be in English, but at least you’ll keep your feet dry !
