The 2017 Eclipse Across America

On August 21, 2017, millions of Americans will witness the first total solar eclipse to cross the continental United States in 99 years. As in all total solar eclipses, the moon will block the sun, revealing its ethereal outer atmosphere—its corona—in a wondrous celestial spectacle.

People in Southeastern Wisconsin will be able to see 85% of the total eclipse between 1:20 pm and 1:23 pm CDT. 

The Eclipse's Path

You can see a partial eclipse, where the moon covers only a part of the sun, anywhere in North America. To see a total eclipse, where the moon fully covers the sun for a short few minutes, you must be in the path of totality. The path of totality is a relatively thin ribbon, around 70 miles wide, that will cross the U.S. from West to East. The first point of contact will be at Lincoln Beach, Oregon at 9:05 a.m. Pacific Time. Over the next hour and a half, it will cross through Oregon, Idaho, Wyoming, Montana, Nebraska, Iowa, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, and North and South Carolina. The eclipse will end near Charleston, South Carolina at 4:09 p.m. Eastern Time.

Safest Ways to Watch

For your own safety please do not look directly into the sun without the use of a filter or eye protection. For more information about what filters are safe to use and when it is safe to look at the eclipse please read up on some of NASA's safety tips.

As people across America gather together to witness the eclipse, scientists look to the skies for a very specific reason: to investigate the secrets of the sun’s elusive atmosphere. The eclipse’s precious seconds of darkness offers us a brief window into how our sun works, how it can produce deadly solar storms, and why its atmosphere is so hot. Join NOVA as they investigate the storied history of solar eclipse science alongside seasoned and citizen-scientists alike as they don their eclipse glasses and tune their telescopes for the eclipse over America.

NOVA - Eclipse Over America premieres on Monday, August 21 at 8:00 pm on Milwaukee PBS channel 10. There will be an encore presentation on Wednesday, August 23 at 7:00 pm.
