Goodbye Summer...Hello Fall!

 

This Saturday, September 22nd, at 10:49 a.m., the sun will be centered directly on the earth's equator resulting in (approximately) equal lengths of both day and night.

 

Here in the Northern Hemisphere this celestial event is referred to as the "Autumnal Equinox" and marks the end of summer and the start of fall.

 

Conversely, in the Southern Hemisphere it is called the "Vernal Equinox" signalling the end of  winter and the start of spring.
