Note that totality for this eclipse only lasts from 2 minutes on the west coast, to about 2 minutes and 41 seconds at maximum near Carbondale, Illinois, and about 2 minutes and 30 seconds when it crosses the east coast. You must be within the path of totality for the Augsolar eclipse to see the real show. If you are standing on the sidewalk in front of the west end of the Performing Arts Center, you will not see any totality at all. In Kansas City, in the middle of the intersection of West 16th Street and Central Street, in front of the Kauffman Center for the Performing Arts, totality lasts just 5.7 seconds. For example, totality lasts 2m 38s in Lanthrop, north of Kansas City, MO. As you move towards the edges of the path of totality, the length of totality is less. Totality lasts the longest on the "centerline" of the eclipse, a line that runs along the exact center of the path of totality. Xavier Jubier's 2017 Eclipse Path of Totality Google Map overlay with local circumstances is the perfect tool to find a place to see the eclipse in the path of totality. Here is the first critical thing you need to know - you absolutely must be within the path of totality to see the corona, prominences and chromosphere. The difference between saying "shrug," and screaming "OH MY GOD!"
You may think "how much of a difference could that make?" Well, all of the difference in the world. If you are just outside of this path, you will not see a total eclipse at all, you will only see a partial eclipse. To see a total eclipse you have to be located in the "path of totality" where the umbra falls. For this eclipse, it is only 60 to 70 miles wide.
This shadow, called the "umbra", is very small where it lands on the face of the Earth. It is this shadow of the Moon that you are standing in during a total solar eclipse. Just as you see your shadow on the ground on a clear sunny day because your body is blocking the Sun's light, the Moon casts a shadow when it blocks the Sun's light.

The corona is about as bright as the full Moon and is safe to look when the Sun is completely covered by the Moon. But during totality, the Moon covers up all of the Sun's photosphere, and the corona becomes visible. This is why the corona is normally invisible - it is lost in the blinding glare of the Sun's brilliance. The solar corona is about 1 million times fainter than the Sun's photosphere, its normally visible surface.

The Moon will appear as a black disk in the center of the corona, a vision that has been described as "the Eye of God." The Moon will block out the incredibly bright light of the surface of the Sun, revealing one of the most amazing sights in all of nature - the delicate and subtle solar corona, the Sun's outer atmosphere. On Monday August 21, 2017, the heavens will declare the glory of physics as the Moon passes in front of the Sun creating a total solar eclipse.
