June 10, 2002
On Monday, June 10th, across much of North America, the setting Sun will become a crescent shape as the Moon eclipses our star. This particular type of eclipse is known as an annular eclipse. During an annular eclipse, the Moon passes directly in front of the Sun but is unable to completely cover it because the Moon's disk appears smaller than the Sun.
The June 10 annular eclipse will be visible from eastern Asia, the Pacific Ocean and much of North America. From some locations, more than 99% of the Sun's disk will be hidden by the Moon. The eclipse will be partial for most observers throughtout this region including the United States and Canada, (except the East Coast), and Mexico.
What the eclipse will look like and when it begins and ends depends on your geographic location. You can see a graphic preview for a number of Canadian cities based on eclipse predictions by Fred Espenak, NASA/GSFC, by following the link below:
Extreme care must be taken when watching a solar eclipse. You should never look directly at the Sun with the naked eye or through any optical device (e.g. - camera, binoculars or telescope).
|Advice from the Ontario Association of Optometrists
To avoid permanent damage to their eyes, the Ontario Association of Optometrists recommends that Canadians exercise caution and never view the Sun directly with the naked eye. The association offers the following advice.
For more information on safe viewing of the eclipse and instructions for making projection devices, follow the YES I Can! Science link below to curriculum-linked classroom activities.
Linked to expectations of the Grade 6 Space strand of the Pan-Canadian Science Curriculum, the guide includes explanations, demonstrations, diagrams and investigations to assist students in understanding and safely viewing solar eclipses. This guide may be adapted for use with both older and younger students and will meet skill expectations for initiating and planning as well as performing and recording.
