When the sun sets tonight in the Northern Hemisphere night will last slightly longer than day. In the Southern Hemisphere day will now last longer than night. In six months time the tables will be turned as North heads back to spring and South to autumn.
Mists and mellow fruitfulness is the phrase from a poem I always think of. Finding mushrooms in the garden, seeing Robins looking for food, seeing the leaves change. Already there are tinges of red and yellow on the bigger trees, I think because, being higher up, their leaves feel the chill first. Driving up the local hill you see more changes. Presumably the trees on the lower slopes are more protected. Perhaps its a micro climate?
In a few months it will be winter. I’m hoping things don’t get too cold. But maybe I should hope for cold to cool the climate?
Happy Autumn Equinox.

Great post.
BTW I wrote a slightly more technical post about the equinox at:

Thank you, very interesting. I particularly liked the part about sunlight being refracted. Also sunlight arrives eight minutes later and stops eight minutes later than when it left the sun. I like the idea that the sun has already set when we see it happen x
