Maybe "umbraphiles" can lay claim to multiple solar eclipses, but the rest of us wait most of a lifetime to see something like a total eclipse.
And here it is... the "American Eclipse," with a path of totality from the Oregon Coast to Charleston, South Carolina.
The Exchange takes a hiatus to allow live coverage of the eclipse.
The BBC will provide that coverage from 8 AM to 11 AM on the News & Information Service of JPR.
Listen at your leisure, or head outside to watch what happens (protect your eyes!).
