Solar Eclipse - 21 August 2017


On August 21, a rare celestial event will be visible across Canada: a partial solar eclipse. 

Don’t miss our webinar on the solar eclipse!

People in a thin band in the United States will have the chance to observe the total eclipse where the Moon will completely cover the Sun. In Canada, the Moon will only cover part of the Sun and the eclipse will be partial. The fraction of the Sun covered by the Moon will range from about 90% in the Vancouver area to less than 20% in the Canadian North.
