The great American solar eclipse will cover our nation like a sash on a beauty queen on Aug. 21. The last time this phenomenon extended from the Pacific to the Atlantic coast was in 1918. Oregon is expecting an overload of visitors to view the eclipse in its totality, but on Whidbey Island, only 90 percent of the sun will be blocked by the moon. Nonetheless, it’s worth observing to see the sun’s corona, the part of the sun that Earthlings get to see only during solar eclipses. The celestial show begins at 9:08 a.m., will reach maximum darkness at 10:20 a.m., and ends at 11:38 a.m.
