The last time a total solar eclipse touched only the U.S. was in 1257 (of course, the U.S as a country didn’t yet exist) and it won’t happen again until 2316. This occurs when the sun, moon and Earth align in a rare event that’s being called the Great American Eclipse. The best way to see it is with special solar eclipse glasses and more than 2 million pairs of them are being distributed for free at 4,800 public libraries throughout the U.S. for the rare total solar eclipse in August. Regular sunglasses will not properly protect your eyes if you plan on catching the eclipse. The eclipse will cross the U.S. on Aug. 21, 2017 and will begin in Oregon at 10:15 a.m. local time. The eclipse’s path of totality will cut a 60-mile wide arc across the country and end in South Carolina about an hour and a half later. The best time to see the eclipse in Arizona will be from 9:15 a.m until Noon, according to timeanddate.com. Locate your nearest local library using the interactive map.
