Reminder: Watch for the 'Super Moon' Saturday Night

In case you missed it earlier this week, here's a reminder that you could be in for a treat Saturday night—if the weather cooperates.

According to astronomers at Discovery.com, the moon will officially become full on Saturday (May 5) at 8:35 p.m. PDT. And because this month's full moon coincides with the moon's perigee—its closest approach to Earth—it will also be the year's biggest.

The lunar orbit is not a perfect circle, so the moon's distance from the earth varies with each revolution. The moon's average distance from Earth is 237,700 miles (382,500 km), but this week the moon will come within 221,802 miles from Earth, causing higher- and lower-than-normal tides in the Puget Sound.

Saturday's forecast calls for partly cloudy skies, so we could be in luck.
