Rare annular solar eclipse on Sunday


A rare "annular" solar eclipse will trek across Western states on Sunday, astronomers report, which is the latest occurrence in a busy year for heavenly events. 
Crossing from Oregon to Texas, the eclipse will darken the center of the sun's disk for 4½ minutes but leave its bright rim visible, a less-than-total eclipse that will still cast the moon's shadow over a roughly 150-mile wide path.
The last annular eclipse was in 1994, and the next one will be in 2030, part of an 18-year cycle. The full eclipse starts in Medford, Ore., at 6:26 p.m. PT, and ends in Lubbock, Texas, at 8:40 p.m. CT. A partial eclipse will be viewable everywhere from San Francisco to Buffalo.
This deepest solar eclipse in decades will blot out most of the sun over Stockton, at a time when the sun will be slowly sinking in the western sky. Stockton is about 200 miles south of the narrow ribbon of Southern Oregon and Northern California from which the moon will obscure all but the sun's outer "ring of fire."
