Once in a Blue Moon

 What is a “blue moon”??  If you have a third grader at TPES, chances are they know the answer.  We have been studying the phases of the moon as part of our third grade solar system unit. 

A “blue moon” refers to the unusual occurrence of a ” second full moon to occur in a calendar month”. *(See below). The good news is we will be lucky enough to have a most unusual blue moon right on New Year’s Eve.  I hope you and your family will be able to get outside and study all the phases of the moon.

To learn more, go to the site below.  It will give you up-to-date information regarding  visible planets, evening constellations,  moon rise,  moon set and more.  Happy gazing!

*( Once in a Blue Moon … “is a common way of saying not very often, but what exactly is a Blue Moon? According to the popular definition, it is the second full moon to occur in a calendar month.  The average time between full moons is about 29.5 days and the length of an average month is roughly 30.5 days. This makes it very unlikely that any given month will contain two full moons, but it does happen.”)
