Jay Pasachoff made the following statement in a CNN article (link):

"Scientifically there are special things we can study on the sun that we can't observe at any other time," says Pasachoff, who will use the few minutes of totality to learn more about the motion and structure of the corona, the sun's outer atmosphere.

I find that hard to believe, with modern coronagraphs, satellites like SDO and SOHO, and so forth. Any comments? --Keith

VERY important - this is still a sensitive test of general relativity. (deflection of star light near the solar limb). Also, refinement of the lunar orbit theory.
