GRAND CANYON, AZ - MAY 20: A woman checks her smart phone while watching the first annular eclipse seen in the U.S. since 1994 with special glasses to protect her eyes on May 20, 2012 in Grand Canyon National Park, Arizona. Differing from a total solar eclipse, the moon in an annular eclipse appears too small to cover the sun completely, leaving a ring of fire effect around the moon. The eclipse is casting a shallow path crossing the West from west Texas to Oregon then arcing across the northern Pacific Ocean to Tokyo, Japan. (Photo by David McNew/Getty Images)
