Lake Wabaunsee Sunset and Blue Moon August 20.  Thanks Dennis Richter for your photos!

On Aug. 20- 21 (from dusk to dawn) will be a blue moon.  Mostly known as the second full moon in a calendar month, it turns out there are more than a few kinds of blue moons out there. The full moon of Aug. 20, 2013, will be considered a seasonal blue moon — the first in nearly three years. Normally, a season has three months, and hence three full moons, but the eccentricities of our calendar mean that once every three years, a season has an extra full moon. The last seasonal blue moon occurred on Nov. 21, 2010, and won’t happen again until May 21, 2016.
