What is a solar eclipse?
A solar eclipse takes place when the moon passes in a direct line between the earth and the sun. The moon’s shadow travels above the earth’s surface, and the sun’s light (as seen from earth) is blocked out.
What is a partial solar eclipse?
A partial solar eclipse takes place when the earth moves through the lunar penumbra as the moon travels between the earth and the sun. It is referred to as ‘partial’ because the moon does not block the entirety of the sun, when witnessed from the earth.
How to see an eclipse
When seeing an eclipse, you should always use approved filters or use an indirect method of seeing it. Never look at the solar eclipse directly as it could blind you or lead to severe eye damage.
