On August 21, 2017 - A Total Eclipse of the Sun
An Animated Grid Map for Over 150 Points Across the U.S.A.
|This map above has over 150 locations animated throughout the United States laid out on a grid. Each animation is one frame per minute. Each location doesn’t represent a particular city, but the overall display gives you a better idea how the eclipse will look across the states. For those interested, you can download the Quicktime file here at a higher resolution.|
Total Eclipse of the Sun as seen in Illinois where greatest (maximum) duration of darkness will occur.

United States Naval Observatory - 2 minutes and 44.3 seconds of darkness, a few miles south of Carbondale Illinois in the
NASA - 2 minutes and 40.2 seconds of darkness near Goreville Illinois, which too, is in the Shawnee National Forest. The exact spot is on farmland with two lane roads nearby. Straight-line distance from Goreville to "greatest duration" is under six miles. The separation from USNO's spot and NASA's is under twenty miles in southern Illinois.
Total Eclipse of the Sun as seen in Kentucky where the greatest eclipse will occur.
|The name of the game is weather: Are the clouds going to interfere with your view of this eclipse on August 21, 2017?
This is how the clouds looked on August 21st from 2012 to 2016 across the lower 48. I am going to hit the road if the
weather looks bad for my location, and I live near Cadiz Kentucky. You should plan to be flexible if the forecast doesn’t
look right! There is nothing worse than being in rain, with the sky being pitch black for over two minutes on August 21st of next year during a solar eclipse!
I hope the skies will be TOTALLY CLEAR, and especially of jets!
Contrails can spoil the view and photographs from the ground.
Read Guy Ottewell's article, Tri-Saros, about how the 2017 eclipse repeats itself, sort of, over the decades.

Moon's orbital plane influencing how the eclipse path looks in 2017 and 2024
|As you can see, the shadow of the Moon is highly influenced by the tilt of its own orbital plane. Of course rotation, distance, speed and so on play a factor too!
A View of the Moon’s Shadow Traveling West to East on August 21, 2017
All frames begins at 13:30 UT. The Moon, along with all other planetary objects, move west to east across the sky. As seen in Oregon, at that same time, the Sun is just rising just above the horizon, while the Sun has already been in the sky for three hours in North Carolina. In both cases, the Moon rose before sunrise towards the east. The Moon is heading towards the Sun from west to east even though the Sun and Moon are being carried westward across the sky due to the Earth's rotation..
You will note that the shadow cone, in the animation, is heading towards the coast of Oregon where a total solar eclipse can be seen in the morning hours. A couple of hours later, the shadow cone will move across the states towards North Carolina where another total solar eclipse will be seen in the afternoon. Again, the shadow is moving west to east.
