What is a solar eclipse?

A solar eclipse is defined as an event when the moon, in its orbit, passes between the sun and earth covering up the sun’s light seen on Earth. It will peak in Illinois around 2:01pm. 

There are three types of lunar eclipses:

• Total: During a lunar eclipse, the sun, Earth, and moon line up perfectly, and the Earth’s shadow completely covers the moon. This can only happen when the moon is close enough to Earth to pass through our planet’s umbra, the darkest part of the shadow.
• Partial: If the moon is too far away to pass through the umbra, it will only partially enter Earth’s shadow. During a partial eclipse, part of the moon appears darkened while the rest remains lit by sunlight.
• Penumbral: The penumbral eclipse is the most common type of eclipse. It happens when the moon passes through Earth’s outer shadow or penumbra. During a penumbral eclipse, the moon darkens slightly, but it’s not as noticeable as a partial eclipse.
