Dear Commons Community,
The autumn equinox is upon us, and with it, a shift to shorter days, longer nights and the astronomical start of fall in the Northern Hemisphere. Autumn officially starts today at 8:43 am (EDT).
Equinoxes occur when Earth reaches a point in its orbit where the sun shines directly on the Equator. This happens twice a year, in March and in September, and is a result of Earth’s spinning on an axis that is tilted 23.5 degrees from the plane of its orbit. During an equinox, places around the globe experience nearly equal periods of day and night.
Happy Fall!
Tony
