Annular eclipse occurs throughout the western USA.

The silhouetted moon covers the sun during an annular eclipse over the skies of Monument Valley National Park, Arizona on May 20, 2012. The eclipse was seen by millions of viewers from China and Japan to the Western USA as the earth's rotation positioned the Far East and USA under the moon's shadow. The two hour long even reached maximum coverage, or annularity, for approximately four minutes as the sun was blocked by the moon at 6:34 PM local time. .UPI/Joe Marino-Bill Cantrell
