RARE SOLAR EVENT: Partial Solar Eclipse Sunday, May 20th!


On Sunday, May 20th, 2012 an annular solar eclipse will be seen across areas of the western United States. The area of full annular eclipse is shown by the red area in the graphic to the right, beginning over the western Pacific Ocean and traveling east at about 1,000 MPH across the ocean to the western U.S. before sunset. This will be the first central eclipse of the 21st century in the continental U.S., and the first annular in the continental U.S. eclipse since May 10th, 1994.

Here in Wyoming, we will see a partial solar eclipse (weather permitting - see forecast below), with 70-75% of the sun's disc obscured at its peak. The event will begin a little after 6 PM and last through sunset (see times below).

The next major eclipse will be a total eclipse that will pass through central Wyoming on August 21st, 2017. Mark your calendars!

Partly cloudy skies as drier air and high pressure continue to build across Wyoming. A few mid or high level clouds may sneak into portions of northwestern Wyoming late.


Looking directly at the sun without a proper solar filter can cause severe eye damage, including blindness; sunglasses do not provide sufficient protection.
