Is there anything more fitting than a full moon on Halloween? The lunar event on Oct. 31 is called a "blue moon"--not for its color or outward appearance--but for its frequency. In this case, it's the rare calendar month that has two full moons. Several Long Island organizations are planning events to help people learn more about the lunar phases:
