Blue moon halloween-RomoloTavani

The skies have a treat for everyone this Halloween.

We'll have a full moon on October 31st, the second one this month, known as a Blue Moon. 

 According to the Farmer's Almanac, a blue moon on Halloween happens only every 19 years so we won't see another one until 2039. 

 October's first full moon, known as a Harvest Moon, rose on October 1st.
