August 21 2017

By the time this 70-mile wide track arrives, the United States will have been waiting 38 years for a total eclipse. It hits land at Salem,

Oregon, during the morning of Monday August 21 and eventually departs into the Atlantic in the early afternoon at Charleston, South Carolina. There are many other cities along the way. The maximum duration of 2 minutes and 40 seconds will be achieved in western Kentucky. This eclipse will also be notable because the bright star Regulus will be only one degree from the eclipsed Sun, so that it will peer through the periphery of the solar corona. Mars and Mercury will also be nearby. As mentioned earlier in the book, this eclipse is the one that follows in the same saronic cycle as that of August 11, 1999, and so their tracks echo each other in Figure 15-7.
