eclipse

At dawn on June 10, some viewers in northern Ontario will have the opportunity to witness what is known as an annular eclipse.

Do you plan to witness the eclipse?

Remember: NEVER LOOK DIRECTLY AT THE SUN.

Intense sunlight can cause instant eye damage. Most “ad hoc” solutions will not protect your eyes. The only way to safely view an eclipse is to purchase authorized ISO filters from a reputable seller.

Solar eclipses occur because the sun is typically about 400 times farther from Earth than the moon and, conveniently, is about 400 times larger than the moon.

As a result, sometimes the moon appears to completely block the sun and its shadow is cast on Earth.

However, sometimes the distance to the Sun is a little less than 400 times the distance to the Moon and in those cases, the Moon does not completely obscure the Sun, but rather leaves a small annulus (annulus) of light around the Sun, there the name Annular Eclipse. .

Where to witness this month’s eclipse?

This year’s annular eclipse is properly visible only to those who live north/northwest of Lake Superior. Starting at dawn (5:32 local time), the sun will already be partially eclipsed.

If we follow the rise of the sun and the moon and speed up time, we will see that the moon gradually finds a position inside the center of the sun, but it will still leave the ring of light around the sun.

Watch this animated simulation of the June 10 annular eclipse as seen from the Nagagamisis Provincial Park region (created with SkySafari 6 Pro):

If you are not far enough north, you will not be able to see the annular eclipse, but you will see a partial eclipse where part of the sun is hidden by the moon.

Feeling the eclipse

For those who find themselves in the path of the annular eclipse, they will be able to enjoy some surprising things:

  • You may notice the sky darken a little, but not as dramatically as during a total eclipse.
  • The sky looks a bit strange (this is because the light is polarized, direct light is hidden)
  • Looking into the shadows of the leaves, you will see multiple images of the annular eclipse within those shadows. The criss-crossing of many leaves creates small pinhole cameras!
  • You may also notice that the birds begin the morning chorus, thinking that it is dawn again.
  • Finally, you may notice a gentle wind rising as the warm air moves toward the center of the colder air (where it is darker in the moon’s almost complete shadow).

    York University will host several programs on June 9 (the day before the eclipse) and June 10 discussing the eclipse.

    The Haudenosaunee Confederacy and the solar eclipse

    Ontario Parks greatly appreciates the assistance and guidance of Melanie Demers, former astronomy instructor at Six Nations Polytechnic.

    It has long been known that a total solar eclipse was important in completing the peace confederation between five of the Haudenosaunee nations (Mohawk, Cayuga, Oneida, Onondaga, and Seneca; the Tuscarora nation was added to the Confederacy later).

    In Haudenosaunee oral history, the Hiawatha wampum is said to have been woven during a total eclipse of the sun, establishing peace between nations.

    Published articles also support that a celestial phenomenon (probably a total solar eclipse) coincided with the founding of the Haudenausonee Confederacy, marked by the creation of the Hiawatha wampum belt.

    According to the investigation, “during a ratification council held at Ganondagan, the sky darkened in a total or near-total eclipse. The time of day was afternoon, since councils are held between noon and sunset. The time of year was Second Hoeing (early July) or Green Corn (late August to early September (Fields, 1997)”[1].

    Other findings have further supported this research. In your online article Dating of the Iroquois Confederacy by Bruce E. Johansen [2], The conclusion of many researchers is that the confederation began around 1142 AD, since that eclipse would have been total in the peace treaty area and is consistent with other archaeological evidence.

    The solar eclipse became an important astronomical tool to mark this great event, an event that represents the founding of one of the oldest democracies.[3] that has lasted for centuries; on which the most powerful country in the world based its own democracy [4].
