If I understand correctly, the eclipse is visible only on the continent of North America.  A major sign from God that being only visible to North Americans sounds like pretty egocentric thinking.
While casting aside astrology, magic, superstition and apocalyptic obsession, I think it is still possible that natural events coincide with events of political and spiritual significance in the world.  The star (probably a comet?) at the Nativity of Christ.  Or in the Chronicles of Narnia when Eustace Clarence says "a star is a flaming ball of gas," and the Father of Stars tells him, "that is only what a star is made of, not what a star IS."  
So I think the eclipse could coincide with a time of crisis in our nation-an erosion of democratic norms, loss of civility and human kindness, erratic, irresponsible leadership as has not been seen before in our history?
