Superstitions will collide on Friday when a full moon will appear in the sky with an added twist: it's Friday the 13th. Just in time to get you ready for the spooky season, this years full moon will be a harvest moon. The harvest moon is the full moon closest to the autumnal equinox which lands on September 23rd this year. According to the Farmers Almanac, the harvest moon could land in either September or October so that farmers could use the light to work extra hours in the field.

There's a lot happening with this Friday the 13th full moon. It will also be what is known as a "micro moon." A micro moon, according to NASA, is a full moon that occurs when the moon is furthest from earth (a point called apogee). At apogee, the moon will cover an area of sky about 14% smaller than it does when it's closest to earth (a point known as perigee that brings us the "super moon").

You're probably wondering why this is such a big deal. Well, a full moon landing on Friday the 13th is kind of rare, according to the Almanac, the last time it happened nationwide was in October 2000, and it won't happen again till August 2049. If you're feeling already feeling superstitious because of Friday the 13th, the full moon may not help ease you at all. You may want to stay in and call it a day. For the rest of us who are completely ready for the spooky season, this is the perfect time to gather and howl at the moon, or just have a Friday the 13th movie marathon.
