On Monday, August 21, the shadow of the Moon will pass over Canada. The event is a solar eclipse. Along a rather long but narrow path which stretches across the continental United States from Oregon to South Carolina, people will see a total solar eclipse.

Across all of Canada, we will see the Moon cover up a portion of the Sun – a partial eclipse. WARNING- never look at the Sun without proper protection. Use properly made solar viewers such as the ones for sale on the RASC estore. These filters are safe to look through with your eyes only (not to be used with other optical devices such as binoculars or telescopes – just your eyes.

Members of the Royal Astronomical Society of Canada plan to set up telescopes on eclipse day to show the various phases of the partial eclipse through telescopes equipped with filters to allow safe viewing.

Be sure to check the centre’s web site the day of the eclipse to see if it is a GO or NO GO.

Please note: in case of cloudy weather, the eclipse cannot be seen.
