May 20 annular eclipse to be on full display at Grand Canyon National Park

On Sunday, May 20, 2012, visitors to both rims of Grand Canyon National Park will be able to view a rare annular eclipse of the sun. The western two-thirds of the country and the southern two-thirds of Arizona will see at least a partial eclipse prior to sunset, but visitors to Grand Canyon National Park will see the moon pass fully in front of the sun, leaving only a ring (or "annula") of sun visible around it.
