The Blue Moon

"Once in a blue moon" is the old cliche. Tonight is that day there will be a blue moon. No the moon will not be blue in color but it will be the second full moon in a month. Well that is what some people say. It is also described as the third full moon in a season. Confusing no? Let's just say it is a big-ish deal if you are a moon fan. This blue moon also has some significance as it occurs on the night of the funeral service for astronaut and moon walker Neil Armstrong.
