On July 27, just after sunset, the longest lunar eclipse of the 21st century will begin. The event will be visible in metropolitan France, but also in the DOM-TOM (except for Polynesia). Unlike the solar eclipse, it represents no danger, you can observe it freely with the naked eye, a rare and poetic phenomenon.
A red moon
Around 21:30 (CEST), the Moon will creep in the shadow of the earth. Contrary to what one might think, our star will not disappear, on the contrary. The rays of the sun that pbad through the earth's atmosphere will tint the moon in a reddish color and thus offer a "dantesque" spectacle, at least for the lucky ones who will have a clear sky.
What time to observe it?
According to astronomers' calculations, the eclipse should last about 103 minutes. A record time that is explained by the position of Moon at its peak (the furthest point of its orbit) which slowed its speed. The highlight of the show will take place around 22:20, the sky will be entirely dark and the Moon will be positioned in the heart of the Earth's shadow.
For those who still want more and who are lucky to have a big telescope, the Mars planet will also be visible at 6 ° just below the Moon, so you can travel the 58 million kilometers that separate us in a fraction of a second. The phenomenon will lose intensity from 23h13 and will end around 0h19.
Different phases of the lunar eclipse:
- 19h15: Moonrise
- 20h24: The Moon enters the penumbra (beginning of the (event)
- 9:30 pm: The Moon enters the shadows
- 10:20 pm: The Moon is at the center of the Earth's shadow (optimal moment to observe it) .
- 11:13 pm: The Moon goes out of the shadow
- 00h19: The Moon pbades in the dim light
- 01h28: The Moon is no longer in the dim light (end of the event) .
