2013 September Equinox

The 2013 September equinox comes on September 22, at 2:44 p.m.EST  (20:44 UTC). In the Northern Hemisphere, the sun is rising later now, and nightfall comes sooner. This is our autumn equinox, when the days are getting shorter in the Northern Hemisphere. At this equinox, day and night are approximately equal in length.

If you live in the Northern Hemisphere, you can easily notice the later dawns and earlier sunsets.  Also notice the arc of the sun across the sky each day. You’ll find it’s shifting toward the south. Birds and butterflies are migrating southward, too, along with the path of the sun.  The shorter days are bringing cooler weather. A chill is in the air.  Creatures of the wild are putting on their winter coats.  All around us, trees and plants are ending this year’s cycle of growth.
