Let Fall Officially Ring!
The Autumnal Equinox has officially arrived here in the Northern Hemisphere! To our Southern Hemisphere readers, happy Vernal Equinox (first day of spring)!
Wednesday, September 22nd at precisely 3:20 p.m. Eastern, 12:20 p.m. Pacific, was the official Autumnal Equinox. Why such an exact time? It has to do with the Earth’s position in its orbit around the sun. At that minute, the Earth was positioned so the Sun’s rays were directly overhead the Equator. In the spring and summer months the Sun’s rays move north of the Equator and in the fall and winter months those rays move south of the Equator. It’s all relative, really. The rays themselves aren’t moving but rather the tilted position of Earth resulting in the sun angle constantly changing.
To celebrate the first day of fall, let’s take a look at some of the foliage pictures you have shared with us on social media.
