Residents of the Northern Hemisphere on Thursday (11.06.2021) contemplated a partial solar eclipse over a strip nearly 500 km long from Canada to Siberia through Europe.

At the height of this “annular eclipse”, it became possible to see the moon slowly passing in front of the sun, transforming it within a short period into a thin luminous ring like the “ring of fire” in the evening.

A small number of the inhabitants of the highest latitudes in an area equal to about 2 percent of the land area were able to witness this event; Northwestern Canada, far northern Russia, and northwest Greenland. In the Arctic, the occultation rate was about 88 percent.

The phenomenon was visible; But partly over North America and a large part of Europe, including France, Britain and Germany, in addition to part of northern Asia. It lasted about two hours between 11 a.m. and 1 p.m. in France, with a peak between 11.55 a.m. and 12.20 p.m.

“Since Germany is south of the central line, the region on Earth that has the greatest possible darkness during a solar eclipse, it appears to us as if the sun is cut off from the upper right of the moon,” said Mariana Wagner, a spokeswoman for the Hamburg Planetarium.

Fans of following the phenomenon had to use special glasses, as experts stressed the need not to watch the event directly, even with sunglasses, because this may cause burns in the eye, which may not be treatable.

This is the first annular eclipse of 2021 and the sixteenth of the twenty-first century. This astronomical phenomenon occurs when the Earth, the Moon and the Sun are on a parallel line.

An annular solar eclipse is a special form of a total solar eclipse. During a complete solar eclipse, the moon pushes itself in its orbit around the Earth to be between the Earth and the Sun, obscuring the latter from the viewpoint of observers on Earth, and then plunging part of the Earth into complete darkness.

This total solar eclipse was seen in Argentina in December 2020.

The total eclipse occurs when the diameter of the moon becomes exactly parallel to the diameter of the sun when viewed from the earth, which plunges part of the earth into darkness for a short period. This phenomenon is rare and the world will witness it on the fourth of next December, but it will only be possible to see it from Antarctica, and the next total solar eclipse in Germany will not come until 2081.
