Even though the full moon is slightly visible tonight (08-21-21) & then illuminates fully tomorrow morning , it is still ONE full moon. Therefore, I don’t agree with the idea that this current full moon is also a blue moon. The name Blue moon is given to the second full moon in a calendar month. This moon is unique, absolutely, but it doesn’t fit the title of a blue moon.
