The Moon constantly begs for out attention. Yes, it has been a while since humans actually visited that celestial body, but now we at least gaze at it from Earth. A lunar eclipse sure begs for attention, as does solar eclipse. Moonrise and moonset correspond to sunrise and sunset. But there just appears to be so much more to the Earth's satellite. Farmer's almanac gives each full moon a special name.
Blue Moon over Buffalo
Two full moons in a single month are the simpler definition of a blue moon. There's also another one that defines a blue moon as the third full moon in a season with four full moons. I will stick with the simpler one :-)
Every 19 years two blue moons happen in a single year. When that happens, it is almost always in January and March thanks to the short month of February in between.
Have fun gazing up!
