[SEASON CHANGE]: HAPPY AUTUMN EQUINOX!!


With leaves changing, baseball's regular season coming to an end and college and NFL football beginning, you know that summer's last fling is upon us. Goodbye to the smell of sunscreen and hello hot apple cider and pumpkin pie.

Meteorologically speaking, autumn began on Sept., 1 but the autumnal equinox marks the astronomical start to the Fall season.

This year, the baton is passed from summer to fall (in the Northern Hemisphere) on Monday, Sept. 22, at 10:29 p.m. EDT.

So what exactly happens during this time?

Twice a year, around March 20 or 21 and Sept. 22 or 23, the sun's most direct rays shine over the Earth's equator. These two days are known as the March (vernal or spring in the Northern Hemisphere) equinox and the September (autumnal) equinox.

The specific time of 10:29 p.m. EDT marks the passage of direct sunlight over the equator from the Northern Hemisphere to the Southern Hemisphere.

During both the vernal and autumnal equinox, day and night are balanced to nearly 12 hours each all over the world.

Instead of a tilt away from or toward the sun, the Earth's axis of rotation is perpendicular to the line connecting the centers of the Earth and the sun during an equinox.

Daylight in the Northern Hemisphere continues to gradually diminish until the winter solstice, which occurs on Dec. 21, 2014. The opposite occurs in the Southern Hemisphere, where daylight continues to grow longer.

Enjoy the cooler breeze and the changes that is upon us all! Happy Autumn to everyone!
