The Annular Solar Eclipse takes place today.
Here is a brief description from eclipse-maps.com:
On May 21, 2012, an annular solar eclipse begins over southeast China and passes over Japan. When the eclipse crosses the International Date Line, the local date becomes May 20. The eclipse then enters the California/Oregon border, passes in the late afternoon over Nevada, Utah, Arizona, a corner of Colorado, New Mexico, and ends at sunset in Texas.
An annular solar eclipse occurs when the Moon’s apparent disk is just smaller than the Sun’s disk and the Sun appears as a brilliant ring. This spectacular sight can only be safely observed with approved solar filters or by projecting an image of the eclipsed Sun onto a flat white surface.

As you can see, the annular eclipse starts at 23:49 UTC, or
7:49 PM Eastern
6:49 PM Central
4:49 PM Pacific
Aside from being an extraordinary space weather event, this eclipse is highly significant consciousness event. Please see separate post for more information.
