Harvest Moon

Be sure to look out into the sky, especially just after sunset!  The Harvest Moon, also known as the Blue Corn Moon among other names, will be out in full force Saturday night and Sunday night (September 29 & 30).  The Harvest Moon is a full moon that occurs near the time of the Autumnal Equinox (harvest time in the United States).  The equinox occurred this year on September 22, 2012.

 

The Harvest Moon is known for its distinct color, usually a red-ish / orange-ish tint, and large size.  The reason why the full moon looks that way is due in part to its low angle in the sky.  The low angle on the horizon allows all of the little dust particles in the atmosphere to scatter and reflect the moonlight.  The moon’s normal blue-ish tint is scattered in a way that the red-ish tint (which our eyes can’t normally discern) becomes most visible.
