Annular solar eclipse occurs in U.S. (19 images)

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.

The Sun is partially covered by the Moon in this image of the Solar Eclipse over the White Tanks Mountains as it happened at Sky Harbor Airport in Phoenix, Arizona on May 20, 2012. The Sun was not fully covered in Phoenix as it was in other parts of the Southwestern United States. UPI/Art Foxall
