The Autumnal Equinox occurred this morning at 4:20AM (I was actually awake and under the stars!) Equinoxes occur twice a year when the tilt of the Earth’s axis (about 23.5 degrees) and Earth’s orbit around the sun combine in such a way that the axis is inclined neither away from nor toward the sun. Today we have nearly as much daytime as nighttime, and it represents the first day of astronomical Fall. You can read more about the Equinox here.

The white asters in our front field are prolific this year and abuzz with activity! Many different kinds of pollinators are at work including this bee. I love the way it’s dusted with pollen!
