Spooky September sky: Full harvest moon falls on Friday the 13th

MADISON, Wis. - Maybe don't forward this article to Jason Voorhees, just to be safe. 

The Harvest Moon will occur on Friday the 13th for the first time in nearly 20 years. The last time this spooky lunar phenomenon transpired was Oct. 13, 2000.  

 

 

The full moon that occurs closest to the autumnal equinox is called a Harvest Moon. Autumn begins in a week and a half, early in the morning on Sept. 23 across southern Wisconsin.  

The name “Harvest Moon” originates from the custom of farmers sometimes needing to work into the night by the light of the moon to prepare their fields for the upcoming winter. 

While typical harvest moons usually appear large and orange, this year's version is a "micro-moon." The new moon is coinciding with apogee -- the point in the Moon's orbit which is farthest from Earth. The moon will appear 14% smaller than a Supermoon and a little less bright in the night sky. 

Peak viewing time across southern Wisconsin will be just after 11:30 p.m. Friday night. While a few clouds might be in the sky, you should be able to see the spooky sight just fine. 

Don’t miss this chance, because the next time the stars (or in this case, moon and calendar) will align will be in 30 years! The next Friday the 13th Full Moon is set for Aug. 13, 2049.
