On the eclipse of August 2017, the moon's shadow will begin to appear on the surface of the Earth in the Pacific region located about 2400 km northwest of the Hawaiian Islands.
Then this shadow will grow and run quickly towards North America. The shadow of the moon will land in Oregon state and then pass through Idaho, Montana, Wyoming, Nebraska, Iowa, Kansas, Missouri, Illinois, Kentucky, Tennessee, North Carolina, Georgia and South Carolina before entering the Atlantic Ocean.
The shadow of the Moon moves on the ground at a speed of nearly 1600km / h. In Illinois, the sun will be completely obscured for the longest time, lasting up to 2 minutes and 40 seconds. Very dangerous for eyes when looking directly at the Sun. Therefore, to observe the eclipse directly need to use eye protection or indirect observation of the eclipse at the eclipse.
