Events Description

 

This year, you can see an annular solar eclipse on June 10 beginning at sunrise in southern Ontario, through Greenland, and ending at sunset in far-eastern Russia. This is the first of the two polar solar eclipses of 2021.

A solar eclipse occurs when the Moon moves between the Sun and the Earth, blocking the Sun’s light and casting a shadow on the Earth. During an annular solar eclipse, the Moon is at apogee (farthest from Earth) and covers only the Sun’s center (the apparent size of the Moon slightly smaller than that of the Sun) while leaving the outer edges visible as a “ring of fire” or annulus. This means that if you live in the part of the world that lies in the path of annularity, you will see the “ring-shaped” eclipse, while regions outside this path will only get to see a partial eclipse with the Moon blocking part of the Sun.

WHEN & WHERE

Depending on where you are located in Canada, you can see the Sun like a “ring of fire” or like a “crescent moon”. The annularity will be visible from parts of northern Ontario, Quebec and Nunavut.The best view of the annulus will be at the coast of Lake Superior northeast of Thunder Bay, Ontario and the western shore of Lake Nipigon.

The communities of Nunavut can also catch a good view of the eclipse with a maximum duration of annularity of three minutes.

The eclipse will be visible early in the morning on June 10, 2021.

In Toronto, the eclipse will begin before the Sun rises at 5:35 AM, reaching its maximum at 5:40 AM and end at 6:38 AM.

In Iqaluit, the eclipse will begin at 5:06 AM and end at 7:13 AM. You will get to see the annular state from 6:06:30 AM to 6:09:33 AM.

Only those in the Path of Annularity will be able to see the full annular “Ring of Fire” phenomenon.

How to View the Solar Eclipse

If the sky is clear (not cloudy), you can view the eclipse by looking at the sun during the time of the eclipse, from a location of your choosing through special solar filters (ISO 12312-2 international standard) made specifically for the purpose of viewing a solar eclipse.

Remember, it is not safe to view the Sun without appropriate filters as it can cause serious damage including complete loss of vision. Regular sunglasses will not protect your eyes.

 

Where to Buy Solar Eclipse Glasses:

  1. Local RASC/Science Centres.
  2. Sky News.ca (Canadian Magazine of Astronomy & Star Viewing) Store Online
  3. List of reputed vendors by NASA

Other Options:

  • Do a science project and make a pinhole projector – How to make a pin hole projector.
  • Welder’s Mask – A welding mask with lens rating of 14 (ONLY THAT) is safe for viewing the eclipse. Do not use a welder’s mask if the lens is damaged, scratched, or if the shade rating is unknown.
  • To capture an eclipse with binoculars, a telescope, or a camera, use a safety-approved, protective solar filter on your lens.
