The darkest part of the eclipse, the totality, is almost as dark as night.
A total solar eclipse occurs when the Moon completely covers the Sun, as seen from Earth. Totality during such an eclipse can only be seen from a very small area on Earth. This area is usually about 100 miles (160 kms) wide and 10,000 miles (16,100 kms) long.
