(KGTV) -- Not only is Halloween on a Saturday this year (cause enough for celebration), but skywatchers are in for another treat: a “Blue Moon.”
NASA says a Blue Moon is a term used for the second of two full moons that occur in the same month. The first event, a Harvest Moon, happened on October 1.
What makes this particular event so rare is the fact that it’s happening on Halloween.
According to the Farmer’s Almanac, such events only happen every 19 years. The next Halloween full Moon won’t be seen again until 2039, followed by 2058, 2077, and 2096,
