By now most everyone knows what the eclipse looked like from the Earth’s view.  Here is an interesting video from NOAA Weather showing the moon’s shadow crossing the United States today from outer space.  It’s quick, so you might wanna replay several times.  In fact, the eclipse did move incredibly fast due to the fact the Earth rotates at about 1,000 miles an hour. Of course the moon is also moving along with the shadow.  So the speed of the eclipse?

Because of the geometry of the Earth’s shape, the shadow will travel faster across its surface and the ends of the eclipse path, and slowest right in the middle.  By using one of the best eclipse calculators out there (thanks to Xavier Jubier!), we can see that the Moon’s shadow (also called the “Umbra”) is moving:

• 2410mph in Western Oregon
• 1747mph in central Nebraska
• 1462mph in Western Kentucky
• 1502mph near Charleston SC
