The All-American Eclipse: Total Solar Eclipse 2017

This guide is a resource for those who would like to view or learn about the eclipse.

Why Eclipses Happen

"This diagram (which is wildly out of scale) shows a side view of the sun-moon-Earth alignment. From anywhere in the penumbra, you will see a partial eclipse. Only from within the tiny area where the dark umbra touches the Earth will you see the sun completely covered and witness a total eclipse." (Source)

1. The date the next total solar eclipse visible from the U.S. will occur is August 21, 2017. Sear this date into your memory banks.

2. A solar eclipse occurs when the Sun, the Moon, and Earth line up, in that order, and the Moon’s shadow falls on Earth.

3. To see a total eclipse, you must be under the dark part of the Moon’s shadow.

4. Every location in the continental U.S. will see at least a partial eclipse.

5. A partial eclipse doesn’t compare to the spectacular total phase of the eclipse. In other words, it’s all about totality.

6. The best spots to view the eclipse (outside of weather concerns) lie on the center line.

7. The total part of the eclipse is the only time you’ll see the Sun’s outer atmosphere. It’s called the corona, the Latin word for “crown.”

8. Except for a filter, you don’t need any equipment to watch the eclipse.

9. You must use an approved solar filter to view the partial phases of the eclipse.

10. You must not use any filter to view the total phase of the eclipse.
