Happy Autumn.....................

Welcome Autumn!

Are you looking forward to Autumn, it has arrived, and with it visions of leaf-peeper caravans snaking their way by brilliantly colored, sun-lit trees along tranquil rural roads, of crisp nights.

At 11:09 Eastern Daylight Time tonight (which is 03:09 Universal Coordinated Time tomorrow), the autumnal equinox arrives.

In the United States and the rest of the northern hemisphere, the first day of the autumn season is the day of the year when the Sun crosses the celestial equator moving southward (on September 22nd or 23rd). This day is known as the Autumnal Equinox. As the Earth travels around the Sun in its orbit, the north-south position of the Sun changes over the course of the year because of the changing orientation of the Earth's tilted rotation axes. The dates of maximum tilt of the Earth's equator correspond to theSummer Solstice and Winter Solstice, and the dates of zero tilt to the Vernal Equinoxand Autumnal Equinox.
