Today is the Spring Equinox in the southern hemisphere; as Robert Macfarlane writes on X (formerly known as Twitter), it's a day of brief poise & pivot when the Sun’s light falls equally on the northern & southern hemispheres.
It is the first day of summer here, the last of summer in the north (where the Harvest Moon is due towards the end of next week).
A good day, says Macfarlane.
