On Thursday, June 10, 2021, people in the Northern Hemisphere will have the opportunity to experience an annual or partial eclipse of the sun.
A solar eclipse occurs when the moon moves between the sun and the earth, casting a shadow on the earth and blocking some or all of the sun’s light in some areas. During an annual eclipse, the Moon is farther away from the Earth, and the Moon appears smaller than the Sun in the sky. Since the moon does not block the full view of the sun, it looks like a dark disk on top of a large, bright disk. It looks like a sack that encloses with a drawstring. People in Canada, Greenland and some parts of northern Russia will experience the annual eclipse.
In some places, visitors may not see this ring around the moon. Instead they will experience a partial solar eclipse. This occurs when the sun, moon and earth are not aligned properly. The sun will have a dark shadow only on one part of its surface. Visitors in parts of eastern America and northern Alaska will see a partial solar eclipse on June 10, along with much of Canada and parts of the Caribbean, Europe, Asia and North Africa.
Partial eclipses are visible in the United States, southeast, northeast, the Midwest, and north Alaska. In many of these places, eclipses occur just before sunrise, in time, and shortly after. This means viewers must have a clear view of the horizon at sunrise to view the eclipse.

How to safely view an annual or partial eclipse
It is never safe to see the sun’s rays directly, even if the sun is partially or often obscured. When viewing a partial solar eclipse or annual solar eclipse, you should wear sunscreen or eclipse glasses throughout the entire eclipse if you want to face the sun. Sunscreen or eclipse glasses are not regular sunglasses; Regular sunglasses are not safe to look at in the sun.
If you do not have sunscreen or eclipse glasses, you can use an alternative indirect method such as a pinhole projector. Pinhole projectors should not be used to see the sun directly, but rather to project sunlight onto a surface. How to read the guide for creating a pinhole viewer.
