aAt the extreme of what’s called an annular eclipse, Earthlings will see the moon slowly slip in front of the sun, turning it for a few minutes into a thin, luminous ring, like a “circle of fire” in the June sky.
A view dedicated to a few residents of the highest latitudes, who are right in the axis: northwest Canada, the far north of Russia, northwest Greenland and the Arctic, where the obscurity of the solar disk will be 87.8%, the Paris-PSL observatory determines.
The annular eclipse will also be visible, but only partially, over northwestern North America, most of Europe, including France and Great Britain, as well as parts of northern North America. From Asia.
At these latitudes, and if the sky is clear, astronomy lovers will be able to observe the part of the sun obscured by the black disk of the moon, 20% in London, 16% at night, 13.2% in Paris, 5.5% in Toulouse and only 2.8% In Marseilles… “The more we go to the southeast, the less the mystery,” explained Florent Delvey of the Paris Observatory, to AFP. -up – on her YouTube channel.
The eclipse will last about two hours, between 11 a.m. and 1 p.m. in mainland France, with a maximum between 11:55 a.m. and 12:20 p.m. It wouldn’t be “too amazing” at these latitudes, but it would still be interesting to watch, according to the astronomer.
In any case, it is necessary not to look at the star directly, even with sunglasses or through a cloud. “Retinal burns can be irreversible,” the expert recalls.
The most curious will have to protect themselves with glasses sold in astronomy stores (beware of used eclipse glasses), or use the means of observing amateur astronomers.
It can also be thought of obliquely, in projecting to the floor, using a piece of cardboard with holes in it, or a skimmer.
This is the first annular eclipse of the year 2021 and the 16th of the 21st century. This astronomical phenomenon occurs during the period of the new moon, when the Earth, Moon and Sun are completely aligned.
If the apparent diameter of the moon is less than the diameter of the sun, part of the crown of fire remains visible. A total eclipse, which briefly plunges a portion of the planet into darkness, occurs when the diameter of the Moon exactly matches the diameter of the Sun as seen from Earth. This phenomenon, rare, can be observed especially from France in August 1999.
