The Blue Moon Rising

Added on by Ellen Halloran.

     The moon doesn't make its appearance over our neighbors' rooftop until about 35 minutes after moonrise.

     Tonight's full moon fits the modern definition of a "blue moon."  It's the second full moon of the month.  An older definition of "blue moon" notes that it is the third full moon out of four within a season.

     Is it possible to have only two full moons within three months?  Go to earthsky.org for questions and answers about "blue moons" and full moons.
