2021 Eclipse Information

June 10, 2021 Annular Solar Eclipse

An annular solar eclipse will occur on June 10, 2021. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometers wide.

This eclipse is notable for the fact that the path of annularity will pass over the North Pole, the only such eclipse in 21st century.

While the eclipse is visible primarily in northern Canada, in Greenland and in north of Russian Far East, in the northeastern United States and Canada, the sun will be partially eclipsed at sunrise, which will be between 5 and 6 A.M (EDT).

Where to see the partial solar eclipse in North America and Europe

Since it all happens at or very soon after sunrise in northeast USA you need to be northeast of a line between New York and Rochester, or thereabouts, to see anything at all.

Manhattan will see a 72% partial solar eclipse and Rochester 78% and Boston 72%, while in Canada, Toronto will get 80%, and Montreal 79%.

In Europe, London will see a 20% partial solar eclipse, Reykjavik in Iceland 60% and Moscow 15%.

Safety First (Eclipse Glasses)

An annular eclipse of the Sun is not safe to look at with the naked eye at any time; use proper safe solar viewing glasses at all stages of this eclipse.

December 4, 2021 Total Solar Eclipse

A total solar eclipse will occur on December 4, 2021. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. This eclipse will be unusual as the path of the total eclipse will move from east to west across West Antarctica, while most eclipse paths move from west to east. This reversal is only possible in polar regions. Its path across Antarctica will cross near Berkner Island, traverse an arc over the continent, exit, and pass over Shepard Island.

Safety First

An total solar eclipse of the Sun is not safe to look at with the naked eye (unless in 100% totality); use safe solar viewing glasses for viewing this eclipse.

* Below shows the total solar eclipse (December 4, 2021) that will be visible over parts of Antarctica. There will also be a partial solar eclipse in parts of Southern Africa and a partial eclipse in Southern Australia and Southern New Zealand.
