In 2023 the fall — or autumnal — equinox landed on Saturday Sept. 22
at 2:50 a.m. Eastern time (6:50 AM UTC) in the Northern Hemisphere.
So - as of 15 minutes ago - Fall is now officially here!!!

Our girls recently did a professional calendar shoot in which this set up was part.

I think a couple of those photos are earmarked for a 2025 calendar. I'm quite proud of my girls and their accomplishments. Yes, I was also the photographer for their most recent shoot. But I feel most of the credit should go to the models. Although I don't know which photo(s) will be used, I liked this one for my personal use.

There are two different ways to carve up the year: Meteorological and astronomical seasons.

Meteorological seasons are defined by the weather. They break down the year into three-month seasons based on annual temperature cycles. By that calendar, fall already started on Sept. 1 https://pbase.com/britestar/image/173967250 and will run until Nov. 31.

But astronomical seasons depend on how the Earth moves around the sun. Equinoxes, when the sun lands equally on both hemispheres, mark the start of spring and autumn. The exact date can vary from year to year. Of the two equinoxes, I prefer Spring, which promises new life and not an entry into hibernation like the Fall one does.

During an equinox, the Sun crosses what we call the “celestial equator”—an imaginary extension of Earth’s equator line into space. The equinox occurs precisely when the Sun’s center passes through this line. As mentioned, that happened about 15 minutes ago.

For those in the Northern Hemisphere, when the Sun crosses the equator going from north to south, this marks the autumnal equinox.
